 : In this talk, I'll speak about Harnack estimates for elliptic and parabolic equations. I will start from the original paper by Harnack and the seminal  contributions by Moser. Then I'll describe how it is possible to generalize such a result  for a class of degenerate/singular parabolic operators whose prototype are the p-Laplacean and porous medium equation. Lastly we consider Harnack estimates at large and the strong connection between potentials and Harnack estimates.
