  Coherent states can be used for diverse applications in quantum physics
including the construction of coherent state path integrals. Most definitions
make use of a lattice regularization; however, recent definitions employ a
continuous-time regularization that may involve a Wiener measure concentrated
on continuous phase space paths. The introduction of constraints is both
natural and economical in coherent state path integrals involving only the
dynamical and Lagrange multiplier variables. A preliminary indication of how
these procedures may possibly be applied to quantum gravity is briefly
discussed.
