General form of the deformation of the Poisson superbracket on   (2,n)-dimensional superspace
  Continuous formal deformations of the Poisson superbracket defined on compactly supported smooth functions on R^2 taking values in a Grassmann algebra with N generating elements are described up to an equivalence transformation for N \ne 2.
