Abstract:We consider antiPoisson superalgebras realized on the smooth Grassmann-valued functions with compact support in R n and with the grading inverse to Grassmanian parity. The lower cohomologies of these superalgebras are found.
IntroductionThe odd Poisson bracket play an important role in Lagrangian formulation of the quantum theory of the gauge fields, which is known as BV-formalism The antibracket possesses many features analogous to those of the Poisson bracket and even can be obtained via "canonical formalism… Show more
Continuous formal deformations of the Poisson superbracket defined on compactly supported smooth functions on R 2 taking values in a Grassmann algebra G n− are described up to an equivalence transformation for n − = 2.

Poisson superalgebras realized on the smooth Grassmann valued functions with compact support in R n have the central extensions. The deformations of these central extensions are found.
“…There can be several supertraces on generalizations of glðkÞ [9]. Apart for such unexpected features, many properties of finite dimensional glðnÞ have analogs for glðkÞ.…”
