On Laplacianness of Hermitian quadratic and bilinear forms in complex normal variables

Shagufta A. Sultan
A set of results are obtained which will give the necessary and sufficient (NS) conditions for a Hermitian quadratic expression or a Hermitian bilinear expression to be distributed as a noncentral generalized Laplacian. The NS conditions are also obtained for Hermitian bilinear forms to be distributed as an Erlang difference.
