Query: Second Cohomology Space of the Lie Superalgebra of contact vector fields
  $\mathcal{K}(2)$ with coefficients in the superspace of weighted densities on
  $S^{1|2}$   We investigate the second cohomology space of the Lie superalgebra
$\mathcal{K}(2)$ with coefficients in the superspace of weighted densities on
the (1,2)-dimentional real superspace. We explicitly give cocycles spanning
this cohomology space.
