The meaning of COMBINATORY LOGIC is a branch of symbolic logic that deals especially with the notion of substitution and the eliminability of variables in favor of special function symbols.
Symbolic logic Further abstraction of systems of inference using symbols for statements and logical connectives ("and", "or", and so forth). Major branches of symbolic logic include: propositional logic predicate logicPredicate logic may be further subdivided into: first-order logic second-order ...
Symbolic logic uses several symbolic logic symbols, called operators, each with its own unique meaning. These include the following: ∀, the universal quantifier, read as for all ∃, the existential quantifier, read as there exists ∧, denoting conjunction, read as and ∨, denoting disju...
Let Σr be a signature with 0, 1 as constants and function symbols for addition x+y, opposite −x, and multiplication x⋅y. Σr is the signature of both rings and fields. We add a function symbol ÷ for division, with the design decision that x÷y is intentionally partial. This ...

You can remember the first two symbols by relating them to the shapes for the union and intersection. A∧BA∧B would be the elements that exist in both sets, in A∩BA∩B. Likewise, A∨BA∨B would be the elements that exist in either set, in A∪BA∪B. In the previous example, ...
These symbols are often used with the superscript 0:\(\varSigma^{0}_{1},\varPi^{0}_{1},\varSigma^{0}_{2},\varPi^{0}_{2},\dots\) . 27. More precisely, we should talk about the event horizon as seen by C because C is in a finite distance from the black hole. ...
symbolic logic or mathematical logic, formalized system of deductive logic, employing abstract symbols for the various aspects of natural language. Symbolic logic draws on the concepts and techniques of mathematics, notably set theory, and in turn has contributed to the development of the foundations ...
