##### Title: A note on strong negative partition relations
Authors: Todd Eisworth (Submitted on 21 Mar 2007) Abstract: We analyze a natural function definable from a scale at a singular cardinal, and using this function we are able to obtain quite strong negative square-brackets partition relations at successors of singular cardinals. The proof of our main result makes use of club-guessing, and as a corollary we obtain a fairly easy proof of a difficult result of Shelah connecting weak saturation of a certain club-guessing ideal with strong failures of square-brackets partition relations. We then investigate the strength of weak saturation of such ideals and obtain some results on stationary reflection. Comments: 23 pages. Covers my talk at the AMS meeting at Miami University. This is essentially in final form, and is more than twice the length of the previously circulated version because of many new results. Comments are welcome Subjects: Logic (math.LO)

The Preface beginns like this: "Ramsey's classical theorem in its simplest form, published in 1930, says that if we put the edges of an infinite graph into two classes, then there will be an infinite subgraph all edges of which belong to the same class. The partition calculus has been developed as a collection of generalizations of this theorem". The o.p.r. (ordinary partition relation) (1)

The most difficult ingredient in this scheme is the second, which often requires close relations to a deep result of Pawlikowski. We describe a new approach that proves directly the game theoretic assertion from the partition relation. This allows solving some open problems of Kocinac.

Hajnal R. Rado Included in series Studies in Logic and the Foundations of Mathematics, 106 Description This work presents the most important combinatorial ideas in partition calculus and discusses ordinary partition relations for cardinals without the assumption of the generalized continuum hypothesis. A separate section of the book describes the main partition symbols scattered in the literature. A chapter on the applications of the combinatorial methods in partition calculus includes a section on topology with Arhangel'skii's famous result that a first countable compact Hausdorff space has cardinality, at most continuum. Several sections on set mappings are included as well as an account of recent inequalities for cardinal powers that were obtained in the wake of Silver's breakthrough result saying that the continuum hypothesis can not first fail at a singular cardinal of uncountable cofinality.

Many of these developments were expounded in Combinatorial Set Theory Partition relations for Cardinals which Rado coauthored with three others and
Advances in theoretical mathematics Professor Richard Rado, FRS, Emeritus Professor of Pure Mathematics in the University of Reading, who died on December 23 at the age of 83, made outstanding theoretical contributions to his subject over a period of more than 50 years. Rado was particularly known for his work in combinatorics, the study of the different ways certain operations can be performed a subject vastly developed over the last three decades. His name is often associated with Ramsey's Theory but Rado's paper, Studien Zur Kombinatorik , which appeared in 1933 is nowadays seen as a landmark and precursor of many subsequent developments. Many of these developments were expounded in Combinatorial Set Theory: Partition Relations for Cardinals In 1978, some felt belatedly, Rado was elected a Fellow of the Royal Society "for his work in combinatorics, including abstract independence structures, transversal theory and extensions of Ramsey's Theory (the partition calculus)". Perhaps the tribute which provided the most moving experience of his life, however, was his visit to the Free University of Berlin in October 1981 to lecture and receive an honorary doctorate. The London Mathematical Society, on whose council he had served from 1948 to 1957 and of which he was successively secretary and vice-president, awarded him the senior Berwick Prize in 1972 for his work on partition relations.

by Sumit Ganguly April 2006 Sumit Ganguly of Indiana University is the author of Fearful Symmetry: India and Pakistan under the Shadow of Nuclear Weapons (Oxford and University of Washington, 2005) and India Since 1980 (Cambridge, forthcoming). This talk was given at the History Institute for Teachers Teaching India Marvin Wachman Fund for International Education , cosponsored by the University of Tennessee at Chattanooga Asia Program and the South Asia Center of the University of Pennsylvania, and made possible by a grant from the Annenberg Foundation. Unbiased at least he was when he arrived on his mission,
Having never set eyes on the land he was called to partition
Between two peoples fanatically at odds,
With their different diets and incompatible gods.

##### Factors Animating the Conflict
Three closely related factors animate this conflict. First, the conflict is really about competing notions of state-building in South Asia. Pakistan was created as the putative homeland of the Muslims of South Asia when the British left the subcontinent. The leaders of the Pakistani nationalist movement argued that with the departure of the British, despite the secular professions of the Congress Party that had brought India its independence, for all practical purposes this would be a Hindu-dominated state, and consequently Muslims would not be treated as equal citizens of India.

##### From the Preface:
"Our aim is to present the most important set-theoretic techniques that have found applications outside of set theory. We think of Volume II as a natural continuation of Volume I of the same text, but it is sufficiently self-contained to be studied separately. The main prerequisite is a knowledge of basic naive and axiomatic set theory. Moreover, some knowledge of mathematical logic and general topology is indispensible for reading this volume. A minicourse in mathematical logic was given in Chapters 5 and 6 of Volume I, and we include an appendix on general topology at the end of this volume. Our terminology is fairly standard. For the benefit of those readers who learned their basic set theory from a different source than our Volume I we include a short section on somewhat idiosyncratic notations introduced in Volume I. In particular, some of the material on mathematical logic covered in Chapter 5 is briefly reviewed. The book can be used as a text in the classroom as well as for self-study."

##### HISTORICAL OVERVIEW
Pakistan, along with parts of western India, contains the archeological remains of an urban civilization dating back 4,500 years. Alexander the Great included the Indus Valley in his empire in 326 B.C., and his successors founded the Indo-Greek kingdom of Bactria based in what is today Afghanistan and extending to Peshawar. Following the rise of the Central Asian Kushan Empire in later centuries, the Buddhist culture of Afghanistan and Pakistan, centered on the city of Taxila just west of Islamabad, experienced a cultural renaissance known as the Gandhara period. Pakistan emerged from an extended period of agitation by Muslims in the subcontinent to express their national identity free from British colonial domination as well as domination by what they perceived as a Hindu-controlled Indian National Congress. Muslim anti-colonial leaders formed the All-India Muslim League in 1906. Initially, the League adopted the same objective as the Congressself-government for India within the British Empirebut Congress and the League were unable to agree on a formula that would ensure the protection of Muslim religious, economic, and political rights.

##### Chapter 2. Review and survey of subject area
The purpose of this chapter is to describe the applicability of previous work on database machine (DBM) architecture, Distributed Databases (DDB) , and Data Dictionaries (DD) , to the DRAT architecture. Although it is assumed that the reader is familiar with the basic concepts of relational databases, parallel processing, and Flynn's taxonomy, some definitions are given, in order that no misapprehensions may arise.
##### 2.1.1 THE NEED FOR DATABASE MACHINES
Traditional general purpose computers are better suited to numerical applications than to the kind of tasks required by the users of databases, which are qualitatively different. (There is no suggestion here that faster 'number-crunchers' are not needed). One problem with using a traditional architecture is that of speed as perceived by the user (if users were satisfied with performance there would be little incentive for developing faster machines). Langdon stated, "programs running on the central processor tend to be the bottleneck to system throughput. The database machine (DBM) is the result of an architectural approach which distributes processing power closer to the devices on which data are stored. Another impetus for the approach is due to LSI (sic) technology.

##### Introduction
Naive set theory considers elementary properties of the union and intersection operators Venn diagrams, the DeMorgan laws, elementary counting techniques such as the inclusion-exclusion principle, partially ordered sets, and so on. This is perhaps as much of set theory as the typical mathematician uses. Indeed, one may "construct" the natural numbers, real numbers, and so on in this framework. However, situations such as Russell's paradox show that some care must be taken to define what, precisely, is a set. However, results in mathematical logic imply it is impossible to determine whether or not these axioms are consistent using only proofs expressed in this language. Assuming they are indeed consistent, there are also statements whose truth or falsity cannot be determined from them. These statements (or their negations!) can be taken as axioms for set theory as well. For example, Cohen's technique of forcing showed that the Axiom of Choice is independent of the other axioms of ZF. (That axiom states that for every collection of nonempty sets, there is a set containing one element from each set in the collection.) This axiom is equivalent to a number of other statements (e.g. Zorn's Lemma) whose assumption allows the proof of surprising even paradoxical results such as the Banach-Tarski sphere decomposition. Thus, some authors are careful to distinguish results which depend on this or other non-ZF axioms; most assume it (that is, they work in ZFC Set Theory).

35. Equivalence Relations
Each equivalence relation on a set Partitions the set into its equivalence classes but also for each Partition of the set there is an equivalence relation

##### Equivalence relations
A relation on A is an equivalence relation if it is reflexive, symmetric and transitive. An example of such is equality on a set. One might think of equivalence as a way to glob together elements that can be considered the same relative to a property. That is elements become indistinguishable relative to the relation. For example in arithmetic we don't think twice about 1/2 and 2/4 as having the same value but they are different objects. In geometry, similarity of triangles is an equivalence relation. A right angled triangle with legs of length 3 and 4 and hypotenuse of length 5 is not the same as one with lengths 6, 8 and 10. Yet, we think of them as equivalent because the ratios of the corresponding sides are the same. For each , we define the equivalency class containing a to be the set of those elements which are equivalent to a . We denote this set by [ a ] although you should be aware that there is no standard notation for this. Some authors use a . Two equivalence classes are either equal or disjoint. In fact

##### Partition of a set
Jump to: navigation search A partition of a set into 6 parts: an Euler diagram representation. In mathematics , a partition of a set X is a division of X into non-overlapping " parts " or " blocks " or " cells " that cover all of X . More formally, these "cells" are both collectively exhaustive and mutually exclusive with respect to the set being partitioned.
##### edit Definition
A partition of a set X is a set of nonempty subsets of X such that every element x in X is in exactly one of these subsets. Equivalently, a set P of nonempty subsets of X , is a partition of X if
• The union of the elements of P is equal to X . (We say the elements of P cover X The intersection of any two elements of P is empty. (We say the elements of P are pairwise disjoint
• The elements of P are sometimes called the blocks or parts of the partition.

It is kept here for documentational purposes only. For talks in later years, visit Gideon Schechtman's GFPA webpage Description: This is/was an interdisciplinary seminar which deals mainly with topics in geometric functional analysis and probability theory, but occasionally also with combinatorics and other fields of mathematics of wide mathematical interest and accessibility. The talks in the seminar are often not about results of the speakers but rather expositions of interesting works done by others. To allow providing full definitions and at least some of the details of the proofs at a convenient pace, each talk usually lasts from two hours (one meeting) to two meetings. The special emphasis on accessibility of the talks makes this seminar suitable for students and working mathematicians with interest in either functional analysis, probability, or combinatorics.

 ISCID Encyclopedia of Science and Philosophy BETA Make Entry Become an Editor Most Popular: ( Help Equivalence Relation by Jimmy Tseng Equivalence relation, a mathematical concept, is a type of relation on a given set that provides a way for elements of that set to be identified with (meaning considered equivalent to for some present purpose) other elements of that set. Equivalence relation is defined in a branch of mathematics called set theory, a vital branch underpinning all branches of mathematics and those fields that use mathematics. The power of an equivalence relation lies in its ability to partition a set into the disjoint union of subsets called equivalence class es. Because of its power to partition a set, an equivalence relation is one of the most used and pervasive tools in mathematics. Introduction measured in hours. How can the mathematician express the idea that 12 is equivalent to, or as mathematicians also say identified with, 24 or 48? In general, take any non-negative integer. Divide this integer by 12 and keep the remainder. Any non-negative number that gives the same remainder in this way is equivalent to any other such number. Hence, 2 is equivalent to 14, 26, 38 Â. By positing that any non-negative number is equivalent to its remainder after division by 12, the mathematician succeeds in gaining a new perspective on the set of non-negative integers. The definition of equivalence relation is based on this simple idea of considering some elements to be equivalent to others under the equivalence relation.

##### The partition function and relation to thermodynamics
In principle, we should derive the isothermal-isobaric partition function by coupling our system to an infinite thermal reservoir as was done for the canonical ensemble and also subject the system to the action of a movable piston under the influence of an external pressure P . In this case, both the temperature of the system and its pressure will be controlled, and the energy and volume will fluctuate accordingly. However, we saw that the transformation from E to T between the microcanonical and canonical ensembles turned into a Laplace transform relation between the partition functions. The same result holds for the transformation from V to T . The relevant energy'' quantity to transform is the work done by the system against the external pressure P in changing its volume from V =0 to V , which will be PV . Thus, the isothermal-isobaric partition function can be expressed in terms of the canonical partition function by the Laplace transform: where is a constant that has units of volume. Thus

• Why is the second argument a set, rather than a sequence variable? Interesting design choice. The notation'' question here is not new syntax for a language, it's just the definition of a particular relation called subclass-partition . In KIF you can define relations that take an arbitrary number of arguments, using a a subclass-partition relation take a variable number of arguments. I decided not to use a sequence variable because that is not a minimal ontological commitment; it imposes an extra logical constraint for the sake of syntactic convenience. A sequence (list) imposes an order. But a class-partition requires no order among the classes. And I wanted the second argument to

On the face of most clocks, hours are represented by integers between 1 and 12. However, since a day has 24 hours after 12 hours, a clock goes back to hour 1, and starts all over again from there. Thus each pair of hours such as 1 and 13, 2 and 14, etc. share one number 1, 2, ...etc., respectively. The same applies when we are interested in more than 24 hours. 25th hour is 1, so are 37th, 49th etc. What we are doing here essentially is that we consider the numbers in each group such as 1, 13, 25, ..., equivalent in the sense that they all are represented by one number (they are congruent modulo 12). Being representable by one number such as we see on clocks is a binary relation on the set of natural numbers and it is an example of equivalence relation we are going to study here.
The concept of equivalence relation is characterized by three properties as follows:
Definition(equivalence relation): A binary relation R on a set A is an equivalence relation if and only if
R is reflexive
R is symmetric, and
