Abstract: |
This paper discuss the generaler porous medium equations with strongly nonlinear sources and convections terms, we obtain some properties of finite diffusing speed of solutions for the these equations or existence and expansion of interfaces to the non-negtive weak solutions, using the Harnack inequalities for nonnegtive weak solutions to the these equations.s; convection; nonnegative weak solutions; Harnack inequality; interfaces. |
