Extinction and Decay Estimates of Solutions for a Class of Porous Medium Equations
- 522 Downloads
The extinction phenomenon of solutions for the homogeneous Dirichlet boundary value problem of the porous medium equation Open image in new window , is studied. Sufficient conditions about the extinction and decay estimates of solutions are obtained by using Open image in new window -integral model estimate methods and two crucial lemmas on differential inequality.
