# nLab group functor

A group functor is a group object in a functor category.

## Terminology

The terminology of group-functors is mainly used in the theory of algebraic groups in algebraic geometry. If $G$ is a group functor the multiplication morphism $\pi:G\times G\to G$ is called group law on $G$. An example of special interest in this context is that of a group scheme.
