Harnack's Inequality for Degenerate and Singular Parabolic Equations Rutilius Taurus Aemilianus At the end of theDegenerate and singular parabolic equations have been the subject of extensive research for the last 25 years. Despite important achievements, the issue of the Harnack inequality for non negative solutions to these equations, both of p Laplacian and porous medium type, while raised by several authors, has remained basically open. Recently considerable progress has been made on this issue, to the point that, except for the singular sub critical range,
