Super-algebras

 In mathematics and theoretical physics, a superalgebra could be a Z2-graded algebra.[1] that's, it's an algebra over a commutative ring or field with a decomposition into "even" and "odd" pieces and a multiplication operator that respects the grading.   The prefix super- comes from the idea of supersymmetry in theoretical physics. Superalgebras and their representations, supermodules, provide an algebraic framework for formulating supersymmetry. The study of such objects is usually called super algebra. Superalgebras also play a vital role in related field of supergeometry where they enter into the definitions of graded manifolds, supermanifolds and superschemes. Let K be a commutative ring. In most applications, K may be a field of characteristic 0, like R or C. A superalgebra over K could be a K-module A with an instantaneous sum decomposition \oplus A_}A=A_\oplus A_ together with a bilinear multiplication A × A → A specified A_\subseteq A_}A_A_\subseteq A_} where the subscripts are read modulo 2, i.e. they're thought of as elements of Z2. A superring, or Z2-graded ring, could be a superalgebra over the ring of integers Z. The elements of every of the Ai are said to be homogeneous. The parity of a homogeneous element x, denoted by |x|, is 0 or 1 in line with whether it's in A0 or A1. Elements of parity 0 are said to be even and people of parity 1 to be odd. If x and y are both homogeneous then so is that the product xy and y+.
