Hölder estimates and large time behavior for a nonlocal doubly nonlinear evolution

Ryan Hynd and Erik Lindgren

Vol. 9 (2016), No. 6, 1447–1482
Abstract

The nonlinear and nonlocal PDE

|vt|p2v t + (Δp)sv = 0,

where

(Δp)sv(x,t) = 2  P.V.n|v(x,t) v(x + y,t)|p2(v(x,t) v(x + y,t)) |y|n+sp dy,

has the interesting feature that an associated Rayleigh quotient is nonincreasing in time along solutions. We prove the existence of a weak solution of the corresponding initial value problem which is also unique as a viscosity solution. Moreover, we provide Hölder estimates for viscosity solutions and relate the asymptotic behavior of solutions to the eigenvalue problem for the fractional p-Laplacian.
