superalgebra

A graded algebra $A$ is said to be a superalgebra if it has a $\mathbb{Z}/2\mathbb{Z}$ grading.As a vector space, a superalgebra has a decomposition into two homogeneous subspaces, $A=A_0\oplus A_1$.The homogeneous subspace $A_0$ is known as the space of even elements of $A$, and $A_1$ is known as the space of odd elements.Let $|a|$ denote the degree of a homogeneous element.That is, $|a|=0$ if $a\in A_0$ and $|a|=1$ if $a\in A_1$.The degree satisfies $|ab|=|a|+|b|$.
