Algebraic group

An **algebraic group** is a group that is also an algebraic variety, where the group operations (multiplication and taking inverses) are given by polynomial functions. More formally, an algebraic group is a set equipped with a group structure and additional structure that satisfies certain properties of being defined over algebraically closed fields. ### Key Concepts 1. **Algebraic Variety**: An algebraic variety is a geometric object defined as the solution set of a system of polynomial equations.
