Asymptotic behavior for nonlocal diffusion equations

- Emmanuel Chasseigne, M. Chaves, J. Rossi
- Mathematics
- 1 September 2006

We study the asymptotic behavior for nonlocal diffusion models of the form ut=J∗u−u in the whole RN or in a bounded smooth domain with Dirichlet or Neumann boundary conditions. In RN we obtain that… Expand

An asymptotic mean value characterization for p-harmonic functions

- J. Manfredi, M. Parviainen, J. Rossi
- Mathematics
- 1 March 2010

We characterize p-harmonic functions in terms of an asymptotic mean value property. A p-harmonic function u is a viscosity solution to Δ p u = div(|∇u| p-2 ∇u) = 0 with 1 < p ≤ ∞ in a domain Ω if and… Expand

A convex-concave problem with a nonlinear boundary condition

- J. García-Azorero, I. Peral, J. Rossi
- Mathematics
- 20 March 2004

In this paper we study the existence of nontrivial solutions of the problem {-Δu+u = u p-2u in Ω, {∂u/∂v = λ u q-2u on ∂Ω, with 1<q<2(N-1)/(N-2) and 1<p≤2N/(N-2). In the concave-convex case, i.e.,… Expand

Fractional Sobolev spaces with variable exponents and fractional p(x)-Laplacians

- U. Kaufmann, J. Rossi, R. Vidal
- Mathematics
- 2017

In this article we extend the Sobolev spaces with variable exponents to include the fractional case, and we prove a compact embedding theorem of these spaces into variable exponent Lebesgue spaces.… Expand

A nonlocal convection–diffusion equation

In this paper we study a nonlocal equation that takes into account convective and diffusive effects, ut=J∗u−u+G∗(f(u))−f(u) in Rd, with J radially symmetric and G not necessarily symmetric. First, we… Expand

On the Fučik spectrum and a resonance problem for the p-Laplacian with a nonlinear boundary condition

- Sandra Martínez, J. Rossi
- Mathematics
- 1 December 2004

In this paper we prove that there exists a first curve of the Fucik spectrum of the problem Δpu=|u|p-2u in Ω with a nonlinear boundary condition given by |∇u|p-2∂u/∂ν=α(u+)p-1-β(u-)p-1 on the… Expand
