  The Heisenberg Lie algebras over an algebraically closed field F of
characteristic p > 0 always admit a family of restricted Lie algebras. We use
the ordinary 1- and 2-cohomology spaces with adjoint coefficients to compute
the restricted 1- and 2-cohomology spaces of these restricted Heisenberg Lie
algebras. We describe the infinitesimal restricted deformations of the
restricted Lie algebras.
