| Abstract: | An intrinsic Harnack estimate and some sup--estimates are established for nonnegative weak solutions of equations of non-Newtonian polytropic filtration ut -- div(|Dum |p-2 Dum) = 0, m(p ~ 1) < 1, m > 0, P > 1. |
| Keywords: | Harnack estimate Sup-estimates Equation of non--Newtonian polytropic filtration |
