摘要: We consider the initial-boundary value problem for finitely degenerate
parabolic equation. We first give sufficient conditions for the blow-up and global existence
of the parabolic equation at high initial energy level. Then, we establish the existence of
solutions blowing up in finite time with initial data at arbitrary energy level. Finally, we
estimate the upper bound of the blow-up time under certain conditions.
