An ‘arrow of time’ in logic always points in one direction. The time operator, introduced in matrix logic, changes all that. The antisymmetric commutator products of the major basis set of logical operators u
Different domains use operators without giving a clear definition of the corresponding notion. In mathematics, more particularly, there is not distinction with those of function , transformation , mapping , arrow , or morphism . Starting from this imprecise notion of operator , we develop, in this...
This tool generates truth tables for propositional logic formulas. You can enter logical operators in several different formats. For example, the propositional formulap ∧ q → ¬rcould be written asp /\ q -> ~r, asp and q => not r, or asp && q -> !r. The connectives ⊤ and ...

In case of a non-commutative multiplication operator, two additional division operators arise, left division\(\div _l\), and right division\(\div _r\), which may or may not differ for a givenA. In the above definition, for left division only\(c \cdot _l b=a\)is required; and for...

The goal of topos theory is to develop a language and an efficient method for the study ofconceptsof local character (as well as constructions on such concepts) that are found in diverse branches of mathematics : topology, algebraic geometry, analytic geometry, . . . . ...

This completes the derivation of the mathematical objects that are denoted by the signs "\(\rightarrow\)" and "\(\Rightarrow\)" in this discussion. It needs to be remembered, though, that not all writers observe this distinction in every context. Especially in mathematics, where the single...
