Abstract:
In this article, we consider the degenerate parabolic equation
on a smoothly bounded domain
,
with homogeneous Dirichlet boundary conditions. The values of
,
and
will vary in different circumstances, and the
solutions will have different behaviors.
Our main goal is to present the sufficient conditions for
blowup,
for gradient blowup, and for the existence of global solutions.
A general comparison principle is also established.
