Lecture
Characters: Linear Algebraic Groups
Description
This lecture introduces characters as regular group homomorphisms from a linear algebraic group to a multiplicative group. Characters can be multiplied, added, and inverted, forming a group of regular functions. Examples include characters of the additive group, multiplicative group, and n-dimensional torus. The lecture also explores the character group's linear independence and the induced homomorphism between character groups of linear algebraic groups.
