Query: Stochastic Generalized Porous Media Equations with Reflection   A non-negative Markovian solution is constructed for a class of stochastic
generalized porous media equations with reflection. To this end, some
regularity properties and a comparison theorem are proved for stochastic
generalized porous media equations, which are interesting by themselves.
Invariant probability measures and ergodicity of the solution are also
investigated.
