Existence of positive solutions for some nonlinear parabolic equations in the half space
Electronic journal of differential equations, Tome 2010 (2010)
We prove the existence of positive solutions to the nonlinear parabolic equation
in the half space $\mathbb{R}^n_{+}, n\geq 2$, 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.
