Page "Supercommutative algebra" Paragraph 5

Any commutative algebra is a supercommutative algebra if given the trivial gradation ( i. e. all elements are even ).

Grassmann algebras ( also known as exterior algebras ) are the most common examples of nontrivial supercommutative algebras.

The supercenter of any superalgebra is the set of elements that supercommute with all elements, and is a supercommutative algebra.
