Description

The aim of this paper is to present a symbolic calculation approach for the basic facts for the Lie a-graded (super) algebra of derivations of the Grassmann algebra of differential forms, the -graded Gerstenhaber algebras, the Frölicher-Nijenhuis algebra of vector-valued differential multi-forms, and the Schouten-Nijenhuis algebra of multi-vector fields. These algebras are the necessary algebraic formalism in order to understand an accelerated observer field (a 3+1 split), as an almost product structure (1,1)-tensor field acting on the Grassmann algebras as the derivation.
