## Abstract

Generalizing the ungraded case one can build up $$\mathbb{Z}_2$$-graded differential calculi over arbitrary $$\mathbb{Z}_2$$-graded $$\mathbb{Z}_2$$-algebras based on their respective Lie superalgebra of graded derivations. Especially for the $$\mathbb{Z}_2$$-graded $$\mathbb{Z}_2$$-algebra (M n|m) of (n+m) × (n+m)-matrices with block-matrix grading (n, m ∈ N0, nm) the resulting differential algebra (Ω g (M n|m), d) coincides— as far as we are interested only in its linear structure - with the cochain complex of the Lie superalgebra sl( n|m) with coefficients in (M n|m). Here we want to point out two remarkable facts about this differential algebra (for proofs see Grosse and Reiter 1999)
