A finite time extinction profile and optimal decay for a fast diffusive doubly nonlinear equation
Abstract In this article, we consider a fast diffusive type doubly nonlinear parabolic equation and study the extinction behavior of a solution at a finite time. We show the complete extinction of a weak solution with a nonnegative initial datum, that is, a weak solution is positive before a finite …
