Abstract

Any algebra herein is intended over a field of characteristic 0. Let E denote the infinite dimensional Grassman algebra. Given a power associative finite dimensional ℤ₂-graded-central-simple A and a supertrace algebra B, so that B belongs to the same variety of A⊗ E, we study conditions on B so that it can be embedded into A⊗Ξ, where Ξ is a supercommutative algebra, called A-universal supermap of B, provided B satisfies all the supertrace identities of A⊗ E. We use this result in order to relate the formal smoothness of B with that of its A-universal supermap.
