The syntax and semantics of Prolog, a programming language, are the sets of rules that define how a Prolog program is written and how it is interpreted, respectively.The rules are laid out in ISO standard ISO/IEC 13211 [1] although there are differences in the Prolog implementations.
Functors used in this manner are analogous to the original mathematical meaning of functor in category theory, or to the use of generic programming in C++, Java or Ada. In Haskell, the term functor is also used for a concept related to the meaning of functor in category theory. In Prolog and related languages, functor is a synonym for function ...
Prolog is a logic programming language that has its origins in artificial intelligence, automated theorem proving and computational linguistics. [1] [2] [3]Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended primarily as a declarative programming language: the program is a set of facts and rules, which define relations.
A functor from G to Set is then nothing but a group action of G on a particular set, i.e. a G-set. Likewise, a functor from G to the category of vector spaces, Vect K, is a linear representation of G. In general, a functor G → C can be considered as an "action" of G on an object in the category C. If C is a group, then this action is a group ...
Quintus Prolog rose to a de facto standard, and significantly influenced the ISO standard for Prolog developed in 1995/6. [1] In addition, while the module system envisaged by the ISO standard deviates from that of Quintus, the Quintus module system is in fact more widely adopted by modern Prolog implementations than that mandated by ISO. [1]
The basic types in Fril are similar to those in Prolog, with one important exception: Prolog's compound data type is the term [broken anchor], with lists defined as nested terms using the . functor; in Fril, the compound type is the list itself, which forms the basis for most constructs.

A functor producing certain geometric objects over S might be represented by a scheme X. For example, the functor taking S to the set of all line bundles over S (or more precisely n- dimensional linear systems ) is represented by the projective space X = P n − 1 {\displaystyle X=\mathbb {P} ^{n-1}} .
