Uniform a priori estimates for slightly subcritical fractional problems

Juan-Carlos Felipe-Navarro, Rosa Pardo

We study the uniform a priori boundedness of positive weak solutions to the fractional semilinear Dirichlet problem in a bounded, convex, …

Null-Lagrangians and calibrations for general nonlocal functionals and an application to the viscosity theory

Xavier Cabre, Iñigo U. Erneta, Juan-Carlos Felipe-Navarro

In this article we build a null-Lagrangian and a calibration for general nonlocal elliptic functionals in the presence of a field of extremals. Thus, our construction assumes the e…

A Weierstrass extremal field theory for the fractional Laplacian

Xavier Cabre, Iñigo U. Erneta, Juan-Carlos Felipe-Navarro

In this paper we extend, for the first time, part of the Weierstrass extremal field theory in the Calculus of Variations to a nonlocal framework. Our model case is the energy funct…

The Neumann problem for the fractional Laplacian: regularity up to the boundary

Alessandro Audrito, Juan-Carlos Felipe-Navarro, Xavier Ros-Oton

We study the regularity up to the boundary of solutions to the Neumann problem for the fractional Laplacian. We prove that if is a weak solution of in , $\mathc…

Semilinear integro-differential equations, II: one-dimensional and saddle-shaped solutions to the Allen-Cahn equation

Juan-Carlos Felipe-Navarro, Tomás Sanz-Perela

This paper addresses saddle-shaped solutions to the semilinear equation in , where is a linear elliptic integro-differential operator with a r…
