Definition:Group Product

Definition

Let $\struct {G, \circ}$ be a group.

The term group product can have two different interpretations:

Group Law

The operation $\circ$ can be referred to as the group law.

Product Element

Let $a, b \in G$ such that $ = a \circ b$.

Then $g$ is known as the product of $a$ and $b$.

Examples of Operations on Group Product

Example: $b x a^{-1} = a^{-1} b$

$b x a^{-1} = a^{-1} b$

Example: $a x a^{-1} = e$

$a x a^{-1} = e$

Example: $a x a^{-1} = a$

$a x a^{-1} = a$

Example: $a x b = c$

$a x b = c$

Example: $b a^{-1} x a b^{-1} = b a$

$b a^{-1} x a b^{-1} = b a$
