Nonlinear degenerate parabolic equations with time dependent singular coefficients
Nonlinear degenerate parabolic equations with time dependent singular coefficients
We are concerned with the nonexistence of positive solutions of the nonlinear parabolic partial differential equations in a cylinder Ω × (0, T) with initial condition u(., 0) = u0(.) ⩾ 0 and vanishing on the boundary ∂Ω × (0, T), given by where \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$\Omega \in \mathbf {R}^N$\end{document} (resp. a …
