Upper bounds for the decay rate in a nonlocal p-Laplacian evolution problem
We obtain upper bounds for the decay rate for solutions to the nonlocal problem λtu(x, t) = ∫ℝn J(x, y)|u(y, t) - u(x, t)|p-2(u(y, t) - u(x, t)) dy with an initial condition u0 ε L1(ℝn) ∩ L(Rn) and a fixed p > 2. We assume that the kernel J is symmetric, bounded (and therefore there is no reg...

| Sumario: | We obtain upper bounds for the decay rate for solutions to the nonlocal problem λtu(x, t) = ∫ℝn J(x, y)|u(y, t) - u(x, t)|p-2(u(y, t) - u(x, t)) dy with an initial condition u0 ε L1(ℝn) ∩ L(Rn) and a fixed p > 2. We assume that the kernel J is symmetric, bounded (and therefore there is no regularizing effect) but with polynomial tails, that is, we assume a lower bounds of the form J(x, y) ≥ c1|x - y|-(n+2λ), for |x - y| c2 and J(x, y) . c1, for |x - y| ≤ c2. We prove that (eqution presented) for q ≥ 1 and t large. © 2014 Esteve et al. |
