Sharp non-existence threshold for a parabolic Hardy-H{é}non equation with quasilinear diffusion

Razvan Gabriel Iagar, Philippe Laurençot

Optimal conditions for initial data leading to non-existence of non-negative solutions to the Cauchy problem for the parabolic Hardy-H{é}non equation $$ \partial\_tu=Δu^m+|x|^σu^p,…
