Symmetrization for fractional nonlinear elliptic problems

Discrete and Continuous Dynamical Systems, 2023
In this note we prove a new symmetrization result, in the form of mass concentration comparison, for solutions of nonlocal nonlinear Dirichlet problems involving fractional p Laplacians. Some regularity estimates of solutions will be established as a direct application of the main result.

Existence of solutions for a nonlinear problem at resonance

Demonstratio Mathematica, 2022
In this work, we are interested at the existence of nontrivial solutions for a nonlinear elliptic problem with resonance part and nonlinear boundary conditions. Our approach is variational and is based on the well-known Landesman-Laser-type conditions.

Nonexistence and optimal decay of supersolutions to Choquard equations in exterior domains [PDF]

, 2012
We consider a semilinear elliptic problem with a nonlinear term which is the product of a power and the Riesz potential of a power. This family of equations includes the Choquard or nonlinear Schroedinger--Newton equation. We show that for some values of

On contact problems for nonlinear parabolic functional differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2004
The results of [3] by W. Jäger and N. Kutev on a nonlinear elliptic transmission problem are extended (in a modified way) to nonlinear parabolic problems with nonlinear and nonlocal contact conditions.
