negation of conjunction
1Negation — For other uses, see Negation (disambiguation). In logic and mathematics, negation, also called logical complement, is an operation on propositions, truth values, or semantic values more generally. Intuitively, the negation of a proposition is… …
2Minimal negation operator — In logic and mathematics, the minimal negation operator u! is a multigrade operator ( u {k}) {k in mathbb{N where each u {k}! is a k ary boolean function defined in such a way that u {k}(x 1, ldots , x k) = 1 if and only if exactly one of the… …

4Boolean algebra (logic) — For other uses, see Boolean algebra (disambiguation). Boolean algebra (or Boolean logic) is a logical calculus of truth values, developed by George Boole in the 1840s. It resembles the algebra of real numbers, but with the numeric operations of… …
5First-order logic — is a formal logical system used in mathematics, philosophy, linguistics, and computer science. It goes by many names, including: first order predicate calculus, the lower predicate calculus, quantification theory, and predicate logic (a less… …
6Complexity class — In computational complexity theory, a complexity class is a set of problems of related resource based complexity. A typical complexity class has a definition of the form: the set of problems that can be solved by an abstract machine M using… …
7Craig interpolation — In mathematical logic, Craig s interpolation theorem is a result about the relationship between different logical theories. Roughly stated, the theorem says that if a formula φ implies a formula ψ then there is a third formula ρ, called an… …

9T-norm fuzzy logics — are a family of non classical logics, informally delimited by having a semantics which takes the real unit interval [0, 1] for the system of truth values and functions called t norms for permissible interpretations of conjunction. They are mainly …
10Propositional calculus — In mathematical logic, a propositional calculus or logic (also called sentential calculus or sentential logic) is a formal system in which formulas of a formal language may be interpreted as representing propositions. A system of inference rules… …
