##### Introduction
Mathematical Logic is the study of the processes used in mathematical deduction. The subject has origins in philosophy, and indeed it is only by nonmathematical argument that one can show the usual rules for inference and deduction (law of excluded middle; cut rule; etc.) are valid. It is also a legacy from philosophy that we can distinguish semantic reasoning ("what is true?") from syntactic reasoning ("what can be shown?"). The first leads to Model Theory, the second, to Proof Theory. Students encounter elementary (sentential) logic early in their mathematical training. This includes techniques using truth tables, symbolic logic with only "and", "or", and "not" in the language, and various equivalences among methods of proof (e.g. proof by contradiction is a proof of the contrapositive). This material includes somewhat deeper results such as the existence of disjunctive normal forms for statements. Also fairly straightforward is elementary first-order logic, which adds quantifiers ("for all" and "there exists") to the language. The corresponding normal form is prenex normal form. In second-order logic, the quantifiers are allowed to apply to relations and functions to subsets as well as elements of a set. (For example, the well-ordering axiom of the integers is a second-order statement). So how can we characterize the set of theorems for the theory? The theorems are defined in a purely procedural way, yet they should be related to those statements which are (semantically) "true", that is, statements which are valid in every model of those axioms. With a suitable (and reasonably natural) set of rules of inference, the two notions coincide for any theory in first-order logic: the Soundness Theorem assures that what is provable is true, and the Completeness Theorem assures that what is true is provable. It follows that the set of true first-order statements is effectively enumerable, and decidable: one can deduce in a finite number of steps whether or not such a statement follows from the axioms. So, for example, one could make a countable list of all statements which are true for all groups.

##### edit Overview
The archetypal association of this kind, one fundamental to the historical origins of algebraic logic and lying at the heart of all subsequently developed subtheories, is the association between the class of Boolean algebras and classical propositional calculus . This association was discovered by George Boole in the , and refined by others, especially Ernst Schroder in the . This work culminated in Lindenbaum-Tarski algebras , devised by Alfred Tarski and his student Adolf Lindenbaum in the Classical algebraic logic, which comprises all work in algebraic logic until about , studied the properties of specific classes of algebras used to "algebraize" specific logical systems of particular interest to specific logical investigations. Generally, the algebra associated with a logical system was found to be a type of

##### Algebraic logic
There is little that is surprising to be said about the algebraic aspect of Watson. All theorems in a Watson theory are equations, implicitly universally quantified over their free variables. We exhibit a set of formal axioms for equational logic which are supported by Watson:
reflexivity:
A A is an axiom for any term A
symmetry:
if A B is a theorem, then B A is a theorem.
transitivity:
if A B is a theorem and B C is a theorem, then A C is a theorem.
We introduce notation A T x ] for the result of substituting the term T for the free variable x in the term A . A formal analysis of substitution will be needed later when abstraction is considered.
substitution:
if A B is a theorem, then C A x C B x ] is a theorem.
generality:
if A B is a theorem, then A C x B C x ] is a theorem.
This logic of equations is familiar to all of us from high school algebra, though its formal study is not entirely trivial. The path not taken here leads to the more usual approach to logic in which propositions rather than terms are taken as basic and propositional connectives and quantifiers are logical primitives. In Watson, the propositional connectives and quantifiers are not logical primitives: they can be defined in terms of the logical primitives of Watson (definition by cases and abstraction) or they can be introduced as user-defined primitives in a Watson theory.

##### Propositional Consequence Relations and Algebraic Logic
First published Tue 19 Dec, 2006 George Boole was the first to present logic as a mathematical theory in algebraic style. In his work, and in that of the other algebraists of the algebraic tradition of logic of the nineteenth century the distinction between a formal language and a mathematically rigorous semantics for it was still not drawn. What the algebraists in this tradition did was to build algebraic theories (of Boolean algebras, and relation algebras) with among other interpretations a logical one. The works of Frege and Russell introduced a different perspective on the way to approach logic. In those works a logic system was given by a formal language and a deductive calculus, namely a set of axioms and a set of inference rules. Let us call such a pair a logical deduction system , and the formulas derivable in the calculus the theorems of the system (nowadays it is common practice to call this kind of calculi Hilbert style calculi). In Frege and Russell's approach a formal (mathematical) semantics of whatever kind (algebraic, model-theoretic, etc.) for the formal languages they used was lacking. The only semantics present was of an intuitive informal kind.

 HELENA RASIOWA, 1917 - 1994 by Algebraic Logic Rasiowa's first monograph The Mathematics of Metamathematics () written jointly with R.Sikorski, contains a comprehensive survey of algebraic theories of logical calculi. Algebraization is applied to classical, intuitionistic, modal and positive logics. The book focuses on metalogical theorems on the predicate calculi of these logics and on an investigation of elementary theories based on them. The main idea underlying the concept of associating algebraic systems with logical calculi is the following: Let be a first order language such that is its set of individual variables, are the binary propositional connectives of is a unary propositional connective and are the quantifiers of Let be a complete algebra such that are binary operations, is a unary operation and and are infinitary operations the common domain of which is the class of all nonempty subsets of By a realization of the language in a nonempty set and in the algebra we mean any mapping which assigns a function to each function symbol of and a function to any predicate symbol of The realization is then extended to all the terms and all the formulas of Let be a valuation of individual variables in a set Then we define: for any individual variable where and for all where is as above.

Algebraicity Conjecture An infinite simple group of finite Morley rank is isomorphic to an algebraic group over an algebraically closed field.
In the second half of my talk, I shall present some recent results from the study of groups of finite Morley rank with pseudoreflection subgroups:

Stuart Barry Cooper (University of Leeds):
The Interactive Structure of Information: Post's Program Revisited Computability theory concerns information with a causal structure. As such, it provides a schematic analysis of many naturally occurring situations.
Emil Post was the first to focus on the close relationship between information, coded as real numbers, and its algorithmic infrastructure. Having characterized the close connection between the quantifier type of a real and the Turing jump operation, he looked for more subtle ways in which information entails a particular causal context. Specifically, he wanted to find simple relations on reals which produced richness of local computability-theoretic structure. To this extent, he was not just interested in causal structure as an abstraction, but in the way in which this structure emerges in natural contexts. "Post's program" was the genesis of a more far reaching research project.

##### Abstract
The challenge is to integrate algebraic, logic and functional programming into a paradigm that can beat imperative programming. This is an old goal, and many have lost faith that it can be achieved. However, there are signs that due to leaps in system complexity and the intricacies of concurrency the (in)famous von Neumann bottleneck is turning into a real limitation on what imperative programming can achieve.
##### Introduction
``How much land does a man need?'' asked Lev Tolstoi, and the answer turned out to be: surprisingly little. ``How many programming languages does a software designer need?'' The answer seems to be: surprisingly many. See below. Of course, well-designed languages are a key to good software design, but while many well designed languages are available (see below), the problem of ill-designed software persists. Why is this so? A refreshing concept for software design is being puth forth at Praxis High Integrity Systems (IEEE Spectrum Software Report ``The Exterminators'', September 2005), but it is nothing new. Years ago, that was the way software was developed. Programmers actually designed their programs - remember flowcharts ? - and wrote ``pseudocode'' before ever beginning to write code. Why has that changed? For the last 20 years, the goal has been to make programming easier and easier by supplying ever more powerful tools - compilers, Visio, programming packages, workbenches, and so on - and by creating higher-level and more abstract languages. Theoretically, these tools should have made the output better, and, used correctly, they would have. Instead, the innovations made programming and coding so easy that literally anyone can write code. Not well-structured code or bug-free code - just code.

Central problems in algebraic logic (like the representation problem) are discussed in connection to other branches of logic, like modal logic, proof theory, model-theoretic forcing and Godel's incompleteness results. Several open problems are posed. We focus on cylindric algebras which are natural algebras of n-ary relations. Relation algebras (which are algebras of binary relation) are mostly only covered insofar as they relate to cylindric algebras. Cylindric and relation algebras were introduced by Tarski, hence the title of the talk. Date received: July 8, 2005

And yetÂwhen you're done staring at the homework, you still probably have a ton of other homework to do. You're not dumb. Everyone at one point has hoped for help with algebra that doesn't involved parents, teachers or tutorials. They can help (well, maybe not always the parents), but often you're still left confused and unsure of how to solve the equations that you were assigned.

In order to distinguish the Boolean part of a Magari algebra, one writes the Magari algebra as the pair or , where is a Boolean algebra. Magari algebras arose as an attempt to treat diagonal phenomena (cf. the diagonalization lemma in ) in the formal Peano arithmetic Arithmetic, formal ) in an algebraic manner.

The black hole epitomizes the revolution wrought by general relativity. It pushes to an extremeÃ¢ÂÂand therefore tests to the limitÃ¢ÂÂthe features of general relativity (the dynamics of curved spacetime) that set it apart from special relativity (the physics of static, Ã¢ÂÂflatÃ¢ÂÂ spacetime) and the earlier mechanics of Newton. Spacetime curvature. Geometry as part of physics. Gravitational radiation. All of these things become, with black holes, not tiny corrections to older physics, but the essence of newer physics.

Although Helena Rasiowa was born in Vienna, her parents were Polish. In 1918 Poland regained its status as an independent nation and Rasiowa's parents moved to Warsaw. She was educated there, obtaining a good secondary school education with music lessons taken at a special music school. After completing her school studies she took a course in business management before entering university. Rasiowa entered the University of Warsaw in 1938 but, after the German invasion of Poland in 1939, the university closed. Rasiowa and her parents moved to Lvov but the Poles were trapped between the Soviets and the Germans and Lvov came under Soviet control. Life there seemed even more difficult than under German occupation, so after a year the family returned to Warsaw. There was an impressive collection of mathematicians at the University of Warsaw at this time including Borsuk Lukasiewicz Mazurkiewicz Sierpinski ... Mostowski and others. They had organised an underground version of the university which was strongly opposed by the Nazi authorities.

##### The Logic of Boolean Algebra
The logical simplicity of boolean algebra enables the construction of powerful, efficient search queries. The concept of boolean algebra is embedded in human psychology, in our very biological understanding of how the world works. It is the foundation for all of mathematics , most of science, and much of philosophy. But more importantly, it is useful for the construction of advanced Internet search queries, and is used throughout the examples in the following pages. The subsections below provide information on boolean expressions , the boolean operators AND OR , and NOT , some boolean tricks , and and a list of boolean capable search sites Expressions . It is easier to understand boolean algebra when we compare it to the familiar arithmetic algebra we learned in school, with the operators +, , x, / combined with operands in expressions like the following: ( a + b ) x c When we know the values of the operands of an algebraic expression, then we can figure out the overall value. For example, if a=2, b =3, and c=4, then the overall value of the above expression is 20.

Read This! The MAA Online book review column reviews of logic as Algebra by Halmos and Givant.
http://maa.org/reviews/logalg.html
##### Reviewed by Mark Johnson
The intent of Logic as Algebra is expressed clearly in its preface: ...to show that logic can (and perhaps should) be viewed from an algebraic perspective. When so viewed, many of its principal notions are seen to be old friends, familiar algebraic notions that were "disguised" in logical clothing. Moreover, the connection between the principal theorems of the subject and well-known theorems in algebra becomes clearer. Even the proofs often gain in simplicity. To this end, authors Paul Halmos and Steven Givant have written a brief, engaging text aimed at both amateurs and professionals, which requires only a course in modern algebra as background. Since one of this book's potential uses is as a course text, an outline of its contents may be helpful:
• What is Logic?
An introductory parable and mini-logic prepare the reader to meet propositional logic.
• Propositional Calculus
A fairly traditional development of propositional logic.

##### Theme of Conference:
The study of constraint satisfaction problems (CSPs) began in the 1970's in artificial intelligence, where this paradigm is now as popular as ever, with hundreds of researchers using this framework to model and solve a wide variety of problems. In 1978, Thomas Schaefer published a seminal paper on the complexity classification of Boolean CSPs, and since then the importance of the CSP in theoretical computer science has continued to grow. For example, many standard complete problems for standard complexity classes are variants of CSPs, and some of the first optimal inapproximability results in combinatorial optimization were proved for certain CSPs. During the last 10 years, researchers studying the complexity of CSPs have discovered deep connections between this framework and many areas of mathematics, the strongest links currently being with universal algebra and lattice theory, logic and finite model theory, and graph theory and combinatorics. The corner-stone of logical and combinatorial approaches to CSP is the fact that many questions about constraint satisfaction can be stated as questions about homomorphisms between relational structures (e.g., graphs). The universal-algebraic approach assigns a finite algebra to every CSP and employs the properties of the algebra to study the properties of the CSP.

Their representability is especially appealing in computer science, since it allows a closer relationship between their language and models. This book gives a careful account of the results and presents some applications of Fork algebras in computer science, particularly in system specification and program construction. Many applications of Fork algebras in formal methods can be applied in many ways, and the book covers all the essentials in order to provide the reader with a better understanding.

CALL FOR TALKS AND PARTICIPATION
Universal Structures in Mathematics and Computing
http://usmc07.rsise.anu.edu.au

The Australian National University
Canberra, Australia
5 - 7 February 2007
Aim:
Starting from very different motivations, various groups of mathematicians and computer scientists have sought to describe abstract structures in great generality. This parallel evolutionary process has led to various groups of researchers working on highly interrelated areas, though unable to effectively communicate with each other due to vastly differing languages.
This workshop aims to bring together researchers working in category theory, universal algebra, logic and their applications to computer science in order to highlight recent advances in these fields and to facilitate dialogue between the different camps. Of particular interest is work which spans two or more of these areas.
