A map is a function, as in the association of any of the four colored shapes in X to its color in Y. In mathematics, a map or mapping is a function in its general sense. [1] These terms may have originated as from the process of making a geographical map: mapping the Earth surface to a sheet of paper. [2]
The map which assigns to every vector space its dual space and to every linear map its dual or transpose is a contravariant functor from the category of all vector spaces over a fixed field to itself. Fundamental group Consider the category of pointed topological spaces, i.e. topological spaces with distinguished points.
Some authors [14] reserve the word mapping for the case where the structure of the codomain belongs explicitly to the definition of the function. Some authors, such as Serge Lang, [13] use "function" only to refer to maps for which the codomain is a subset of the real or complex numbers, and use the term mapping for more general functions. In ...
A function: between two topological spaces is a homeomorphism if it has the following properties: . is a bijection (one-to-one and onto),; is continuous,; the inverse function is continuous (is an open mapping).
A category C consists of two classes, one of objects and the other of morphisms.There are two objects that are associated to every morphism, the source and the target.A morphism f from X to Y is a morphism with source X and target Y; it is commonly written as f : X → Y or X Y the latter form being better suited for commutative diagrams.
The arrows or morphisms between sets A and B are the functions from A to B, and the composition of morphisms is the composition of functions. Many other categories (such as the category of groups, with group homomorphisms as arrows) add structure to the objects of the category of sets or restrict the arrows to functions of a particular kind (or ...

For example, UPSC papers in India, SAT papers in U.S. and GCSE and A level papers in UK are being sold, as well as other exams worldwide. Previous year question (PYQ) papers are to assess student's brilliancy and capabilities. Students who are preparing for competition exams generally look for past papers.
