Existence and non-existence results for a fractional Lane-Emden equation with nonlocal Neumann conditions

Eleonora Cinti, Matteo Talluri, Tobias Weth

We consider the fractional Lane-Emden equation with a nonlocal Neumann condition in a half-space. We establish the existence of non-constant solutions for the critical problem in a…

Fractional Dirichlet problems with an overdetermined nonlocal Neumann condition

Michele Gatti, Julian Scheuer, Tobias Weth

We investigate symmetry and quantitative approximate symmetry for an overdetermined problem related to the fractional torsion equation in a regular open, bounded set $Ω\subseteq \…

Ground state solutions to generalized nonlinear wave equations with infinite-dimensional kernel

Rainer Mandel, Tobias Weth

The present paper is devoted to existence results for time-periodic solutions of generalized nonlinear wave equations in a closed Riemannian manifold M. Our main focus lies on the…

Second radial eigenfunctions to a fractional Dirichlet problem and uniqueness for a semilinear equation

Mouhamed Moustapha Fall, Tobias Weth

We analyze the shape of radial second Dirichlet eigenfunctions of fractional Schrödinger type operators of the form in the unit ball in with a nond…
