Asymptotically linear fractional problems with mixed boundary conditions

Giovanni Molica Bisci, Alejandro Ortega, Luca Vilasi

We derive the existence of solutions for an asymptotically linear equation driven by the spectral fractional Laplacian operator with mixed Dirichlet-Neumann boundary conditions. Wh…

Fractional critical systems with mixed boundary conditions

R. Kumar, A. Ortega

In this paper, we analyze the existence of solution for a fractional elliptic system coupled by critical nonlinearities and endowed with mixed Dirichlet-Neumann boundary conditions…

Nonlocal critical problems with mixed boundary conditions and nearly resonant perturbations

Eduardo Colorado, Giovanni Monica Bisci, Alejandro Ortega +1

We consider the following nonlocal critical problem with mixed Dirichlet-Neumann boundary conditions, \begin{equation} \left\{ \begin{array}{ll} (-Δ)^su=λu+|u|^{2_s^*-2}u &\text{…

New functional inequalities with applications to the arctan-fast diffusion equation

Rafael Granero-Belinchón, Martina Magliocca, Alejandro Ortega

In this paper, we prove a couple of new nonlinear functional inequalities of Sobolev type akin to the logarithmic Sobolev inequality. In particular, one of the inequalities reads $…

Positive solutions for a weighted critical problem with mixed boundary conditions

Alejandro Ortega, Luca Vilasi, Youjun Wang

We analyze the existence and multiplicity of positive solutions to a nonlocal elliptic problem involving the spectral fractional Laplace operator endowed with homogeneous mixed Dir…
