superalgebra

In mathematics and theoretical physics, a superalgebra over a field K is another name for a Z2-graded algebra over K. Specifically, a superalgebra is a super vector space A = A0 ⊕ A1 over K together with a bilinear multiplication which is an even morphism of super vector spaces. This means that where the subscripts are read modulo 2.
