Abstract:
We prove the existence of positive solutions to the
nonlinear parabolic equation
in the half space
,
,
subject to
Dirichlet boundary conditions. The function f is nonnegative
continuous non-increasing, and the potential p is nonnegative
and satisfies some hypotheses related to the parabolic Kato
class. We use potential theory arguments to prove our main result.
