| Authors: | Hongjun Yuan |
| Abstract: | The aim of this paper is to discuss the extinction and positivity for the non-Newtonian polytropic filtration equation \frac{∂u}{∂t} = \frac{∂}{∂x}(|\frac{∂u^m}{∂x}|^{p-2}\frac{∂u^m}{∂x}) with m > 0, p > 1. |
| Keywords: | Quasilinear degenerate parabolic equations extinction and positivity |
