Let us start by considering the following: Graded commutative superalgebras. That is, A = A 0 ⊕A1, a Z 2-graded algebra over a field k (of characteristic ≠ 2) where ab = (-1)|a||b| ba, for all homogeneous elements a, b. The Quantum plane Cq [X, Y], That is C [X, y] where xy = q -1 yx. The Quantum superplane (or q-Grassman algebra) Cq [ξ, η]. That is C[ξ, η] with, ξ2 = η2 = 0, ξη = -qηξ.
