Query: Induced Chiral Supergravities in 2D   We analyze actions for 2D supergravities induced by chiral conformal
supermatter. The latter may be thought as described at the classical level by
superspace actions invariant under super-reparametrization, super-Weyl and
super-Lorentz transformations. Upon quantization various anomalies appear which
characterize the non-trivial induced actions for the supergravitational sector.
We derive these induced actions using a chiral boson to represent the chiral
inducing matter. We show that they can be defined in a super-reparametrization
invariant way, but with super-Weyl and super-Lorentz anomalies. We consider the
case of $(1,0)$ and $(1,1)$ supergravities by working in their respective
superspace formulations and investigate their quantization in the conformal
gauge. The actions we consider arise naturally in off-critical heterotic and
spinning strings. In the conformal gauge, they correspond to chiral extensions
of the super-Liouville theory.
