Abstract

Category theory starts with the observation that many properties of mathematical systems can be unified and simplified by a presentation with diagrams of arrows. Each arrow f : XY represents a function; that is, a set X, a set Y, and a rule xf x which assigns to each element xX an element f xY; whenever possible we write f x and not f(x), omitting unnecessary parentheses.
