Concurrency Abstracts Boolean logic treats disjunction and conjunction symmetrically and algebraically. Its algebraic structure is essentially that of linear logic, with its morphisms being consequence-preserving renamings of propositions, and with its operations forming the core of a natural concurrent programming language. Algebraic operations on schedules can then be defined as constructions in the category of schedules. boole.stanford.edu /abstracts.html   (205 words)

LEARN BOOLEAN ALGEBRA Boolean algebra is extensively used in relay logic or "ladder diagrams", and in electronic circuitry to build computers and other logic circuits. RTES (Real Time Expert System) allows the basic boolean operators to co-exist in the same expression with conventional algebra operators (+,-,*,/,etc.) as well as comparison operators (greater-than, less-tan, greater-than-or-equal, less-than-or-equal) so that it becomes possible to handle logic that involves analog operands (variables) just as easily as strictly binary logic. You may combine several boolean operators in the same expression to render a given logical condition. www.rt-sys.com /bool.htm   (503 words)

What is Boolean logic? - A Word Definition From the Webopedia Computer Dictionary (bool´ē-&n loj´ik) (n.) Named after the nineteenth-century mathematician George Boole, Boolean logic is a form of algebra in which all values are reduced to either TRUE or FALSE. Boolean logic is especially important for computer science because it fits nicely with the binary numbering system, in which each bit has a value of either 1 or 0. This tutorial covers the basics of Boolean logic and discusses the three distinct manifestations of Boolean logic on Internet search engines. www.pcwebopedia.com /Boolean_logic.htm   (121 words)

Converting truth tables into Boolean expressions - Chapter 7: BOOLEAN ALGEBRA - Volume IV - Digital They allow us to derive a Boolean expression -- and ultimately, an actual logic circuit -- from nothing but a truth table, which is a written specification for what we want a logic circuit to do. Here, Boolean algebra proves its utility in a most dramatic way. Three other rows of the truth table have an output value of 1, so those rows also need Boolean product expressions to represent them: www.allaboutcircuits.com /vol_4/chpt_7/9.html   (121 words)

Boolean Algebra Boolean Algebra is both a formalization of the algebraic aspects of logic, and the customary language of logic used by the designers of computers. An important aspect of the axioms and properties of Boolean Algebra (and therefore of logic as well) is the notion of "duality". All of properties of the logical operators which we have previously discussed can be represented using the symbols of Boolean Algebra. www.rwc.uc.edu /koehler/comath/24.html   (892 words)

Untitled Document Strictly speaking, one knew how to direct the computer in a search for a legal sequence of moves from the beginnings of the system that would constitute a proof that "Robbins algebras are Boolean." The computer needed no meaning, no idea of truth. Boole did not just symbolize logic, he saw that ordinary algebra could be interpreted as logic. Along with this advent of non-Euclidean geometry there came the rise of symbolic logic, particularly at the hands of George Boole, who saw an analogy between algebra and logic. www.isss.org /members/papers/sysround.htm   (892 words)

Ian Hodkinson: Atom structures Perhaps the oldest case is boolean algebra, which corresponds closely to propositional logic, or the logic of unary relations. As with boolean algebra, the notion of a cylindric algebra is defined axiomatically.

Concurrency Abstracts Boolean logic treats disjunction and conjunction symmetrically and algebraically. Its algebraic structure is essentially that of linear logic, with its morphisms being consequence-preserving renamings of propositions, and with its operations forming the core of a natural concurrent programming language. The algebra is that of a parallel programming language expanded to the language of full linear logic, Girard's axiomatization of which is satisfied by the event space interpretation of this language. boole.stanford.edu /abstracts.html   (892 words)

Boole That the symbolic processes of algebra, invented as tools of numerical calculation, should be competent to express every act of thought, and to furnish the grammar and dictionary of an all-containing system of logic, would not have been believed until it was proved. Boolean algebra has wide applications in telephone switching and the design of modern computers. Boole approached logic in a new way reducing it to a simple algebra, incorporating logic into mathematics. www-groups.dcs.st-and.ac.uk /~history/Mathematicians/Boole.html   (1797 words)

Boolean Algebra Boolean Algebra has a connection with set theory and symbolic logic, other areas of math which help to bring together all of math. In the "classical" Boolean Algebra, which is tied to symbolic logic, logical statements are symbolically represented by letters such as A, B, C,. Boolean Algebra may operate on practically any kind of set, and when a Boolean equation is "solved", the result is only one of two items: TRUE or NOT TRUE. www.jairosoft.com /intro_math12.htm   (2385 words)

Boolean Algebra Revisited - Page 1 Boolean algebra became a systematic method of dealing with symbolic logic and a much used method of arguing about the fundamentals of mathematics. Boolean algebra provides an algebraic method of working with all types of digital circuitry, including integrated circuit gates and circuits based on physical switch contacts.

The Mathematics of Boolean Algebra Boolean algebra is the algebra of two-valued logic with only sentential connectives, or equivalently of algebras of sets under union and complementation. Much of the deeper theory of Boolean algebras, telling about their structure and classification, can be formulated in terms of certain functions defined for all Boolean algebras, with infinite cardinals as values. The study of Boolean algebras has several aspects: structure theory, model theory of Boolean algebras, decidability and undecidability questions for the class of Boolean algebras, and the indicated applications. plato.stanford.edu /entries/boolalg-math   (2064 words)

Boolean Algebra The structure of symbolic logic, switching circuits, probability theory and set theory is captured by Boolean Algebra. To describe symbolic logic as an algebraic system we need only give the objects and the operations which will be used to combine the objects. The purpose of this section is to explicitly formulate the structure of Boolean Algebra in the most efficient manner possible. www.eg.bucknell.edu /~cs320/1995-fall/Boolean-Algebra.html   (2458 words)

BRICS-RS-95.bib Complementation is an important operation because it is fundamental for treating the logical connective ``not'' in decision procedures for monadic secondorder logics.\bibpar Subsequently, Diekert and Muscholl solved the complementation problem by showing that with a Muller acceptance condition, deterministic automata suffice for recognizing $\omega $-regular trace languages. We discuss text processing, Boolean circuits, and distributed systems.\bibpar Our main example is an automatic proof of properties for the ``Dining Philosophers with Encyclopedia'' example by Kurshan and MacMillan.

Boolean algebra In mathematics and computer science, Boolean algebras, or Boolean lattices, are algebraic structure s which "capture the essence" of the logic al operations AND, OR and NOT as well as the corresponding set theoretic operations intersection, union and complement. The two-element Boolean algebra is also important in the general theory of Boolean algebras, because an equation involving several variables is generally true in all Boolean algebras if and only if it is true in the two-element Boolean algebra (which can always be checked by a trivial brute force algorithm). Specifically, Boolean algebra was an attempt to use algebraic techniques to deal with expressions in the propositional calculus. www.worldhistory.com /wiki/B/Boolean-algebra.htm   (348 words)

THE LEGEND OF JOHN VON NEUMANN Professor Halmos' research is mainly measure theory, probability, ergodic theory, topological groups, Boolean algebra, algebraic logic, and operator theory in Hilbert space. About 60 of them are on pure mathematics (set theory, logic, topological groups, measure theory, ergodic theory, operator theory, and continuous geometry), about 20 on physics, about 60 on applied mathematics (including statistics, game theory, and computer theory), and a small handful on some special mathematical subjects and general non-mathematical ones. Once when he saw some of us at a blackboard staring at a rectangle that had arrows marked on each of its sides, he wanted to know that what was. users.lk.net /%7Estepanov/mnemo/legende.html   (348 words)

Viktor Kuncak and Martin Rinard: The First-Order Theory of Sets with Cardinality Constraints is Decidable Specifically, we examine the first-order theory that combines 1) Boolean algebras of sets of uninterpreted elements and 2) Presburger arithmetic operations. For example, we obtain decidability of monadic second-order logic of n-successors extended with sets of uninterpreted elements and their cardinalities, a result which is in contrast to the undecidability of extensions of monadic-second order logic over strings with equicardinality operator on sets of strings. Our language allows relating the cardinalities of sets to the values of integer variables. cag-www.lcs.mit.edu /~vkuncak/artifacts/bapa   (348 words)

The Future of Set Theory by S.Shelah Still, even between people working on boolean algebras and the topology of extremely disconnected compact topological spaces there are differences: are you interested in free sets as an Boolean Algebraist or independent sets as a topologist? Products of regular cardinals and cardinal invariants of products of Boolean algebras. The other side of this is that if Yuri Gurevich had not left Beer-Sheva and mathematics, we would probably have an additional volume or two on monadic logics and ramifications by now. shelah.logic.at /E16/E16.html   (2385 words)
