Lie groups | Representation theory
In mathematics, an algebraic representation of a group G on a k-algebra A is a linear representation such that, for each g in G, is an algebra automorphism. Equipped with such a representation, the algebra A is then called a G-algebra. For example, if V is a linear representation of a group G, then the representation put on the tensor algebra is an algebraic representation of G. If A is a commutative G-algebra, then is an affine G-scheme. (Wikipedia).

Algebraic Structures: Groups, Rings, and Fields
This video covers the definitions for some basic algebraic structures, including groups and rings. I give examples of each and discuss how to verify the properties for each type of structure.

Group equation examples Lesson 26
In this video we solve algebraic expressions using the properties of groups. It is always good to work through a few examples. You must get familiar with solving equations where the variables are group elements and not placeholders for numbers only.

Solving Algebraic Fractions | Algebra | Maths | FuseSchool
Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In part 1 we saw how to simplify, and add and subtract algebraic fractions. We discovered that algebraic fractions follow th
