Harnack-type estimates and extinction in finite time for a class of anisotropic porous medium type equations
Eurica Henriques, Simone Ciani
In this work we are interested in the study of a class of anisotropic porous medium-type equations whose prototype is \[ u_t =\sum_{i=1}^N \left( m_i u^{m_i-1} u_{x_i} \right)_{x_i…

The impact of intrinsic scaling on the rate of extinction for anisotropic non-Newtonian fast diffusion
Simone Ciani, Eurica Henriques, Igor Skrypnik
We study the decay towards the extinction that pertains to local weak solutions to fully anisotropic equations whose prototype is \[ \partial_t u= \sum_{i=1}^N \partial_i (|\partia…
