 Commutative diagram

A commutative diagram is a diagram of objects and morphisms in which every two directed paths with the same endpoints define the same morphism.

A **commutative diagram** is a graphical representation used in mathematics, particularly in category theory and algebra, to illustrate relationships between different objects and morphisms (arrows) in a structured way. The key feature of a commutative diagram is that the paths taken through the diagram yield the same result, regardless of the route taken.
