Query: On supermatrix models, Poisson geometry and noncommutative
  supersymmetric gauge theories   We construct a new supermatrix model which represents a manifestly
supersymmetric noncommutative regularisation of the $UOSp(2\vert 1)$
supersymmetric Schwinger model on the supersphere. Our construction is much
simpler than those already existing in the literature and it was found by using
Poisson geometry in a substantial way.
