Query: Advances in Multi-Dimensional Simulation of Core-Collapse Supernovae   We discuss recent advances in the radiative-hydrodynamic modeling of core
collapse supernovae in multi-dimensions. A number of earlier attempts at fully
radiation-hydrodynamic models utilized either the grey approximation to
describe the neutrino distribution or utilized more sophisticated multigroup
transport methods restricted to radial rays. In both cases these models have
also neglected the O(v/c) terms that couple the radiation and matter strongly
in the optically thick regions of the collapsed core. In this paper we present
some recent advances that resolve some shortcomings of earlier models.
