52Is logic empirical? — is the title of two articles that discuss the idea that the algebraic properties of logic may, or should, be empirically determined; in particular, they deal with the question of whether empirical facts about quantum phenomena may provide grounds …

54Sole sufficient operator — A sole sufficient operator or a sole sufficient connective is an operator that is sufficient by itself to generate all of the operators in a specified class of operators. In logic, it is a logical operator that suffices to generate all of the… …
55Monoidal t-norm logic — Monoidal t norm based logic (or shortly MTL), the logic of left continuous t norms, is one of t norm fuzzy logics. It belongs to the broader class of substructural logics, or logics of residuated lattices;[1] it extends the logic of commutative… …
56Converse implication — is the converse of implication. That is to say; that for any two propositions P and Q, if Q implies P, then P is the converse implication of Q. It may take the following forms: p⊂q, Bpq, or p←q Contents 1 Definition 1.1 Truth table 1.2 …
57Computation tree logic — Computation tree logic (CTL) is a branching time logic, meaning that its model of time is a tree like structure in which the future is not determined; there are different paths in the future, any one of which might be an actual path that is… …

60Logical biconditional — In logic and mathematics, the logical biconditional (sometimes known as the material biconditional) is the logical connective of two statements asserting p if and only if q , where q is a hypothesis (or antecedent) and p is a conclusion (or… …
