Cartesian closed category
TYPE OF CATEGORY IN CATEGORY THEORY
Cartesian-closed category; Cartesian closed; Cartesian closed categories; Locally cartesian closed category; Cartesian closedness; Bicartesian closed category
In category theory, a category is Cartesian closed if, roughly speaking, any morphism defined on a product of two objects can be naturally identified with a morphism defined on one of the factors. These categories are particularly important in mathematical logic and the theory of programming, in that their internal language is the simply typed lambda calculus.
