Query: Representation of Semigroups in Rigged Hilbert Spaces: Subsemigroups of
  the Weyl-Heisenberg Group   This paper studies how differentiable representations of certain
subsemigroups of the Weyl-Heisenberg group may be obtained in suitably
constructed rigged Hilbert spaces. These semigroup representations are induced
from a continuous unitary representation of the Weyl-Heisenberg group in a
Hilbert space. Aspects of the rigged Hilbert space formulation of time
asymmetric quantum mechanics are also investigated within the context of the
results developed here.
