Abstract

We consider on Riemannian manifolds the non-linear evolution equation ρ∂ tu=Δpuq. Assuming that the manifold satisfies a (weighted) Sobolev inequality and under certain assumptions on p, q and function ρ, we prove that weak subsolutions to this equation have a finite extinction time. In particular, our main result holds in the case of a Cartan-Hadamard manifold.
