S. E. Konstein, I. V. Tyutin P. N. Lebedev Physical Institute, Russian Academy of Sciences
Abstract:
The Poisson superalgebra realized on smooth Grassmann-valued functions with compact support has a central extension at some values of the superdimension. We find formal deformations of these central extensions.
Keywords:
Grassmann algebra, Poisson superalgebra, central extension, cohomology, deformation, quantization, $*$-commutator.
