Multiplicity of positive solutions for a class of fractional Schrödinger equations via penalization method

Annali di Matematica Pura ed Applicata, 2017
By using the penalization method and the Ljusternik–Schnirelmann theory, we investigate the multiplicity of positive solutions of the following fractional Schrödinger equation ε2s(-Δ)su+V(x)u=f(u)inRN\documentclass[12pt]{minimal} \usepackage{amsmath ...

Existence of positive solutions for a singular fractional boundary value problem

, 2017
We study the existence of positive solutions for a nonlinear Riemann–Liouville fractional differential equation with a sign-changing nonlinearity, subject to multi-point fractional boundary conditions.

ON POSITIVE SOLUTIONS OF ELLIPTIC EQUATIONS

Mathematics of the USSR-Sbornik, 1971
In this paper the authors study weak solutions of elliptic equations of the form in a bounded domain . It is assumed known about these solutions either that they are positive, or that estimates in certain norms hold for their negative parts. It is assumed moreover that an estimate on the -norm of the solution holds on some subdomain .

Regularity and positivity of the solution

2017
In this section we show a regularity result1 that allows us to say that a nonnegative solution to (2.1.1) is bounded.

Symmetry-breaking at positive solutions

ZAMP Zeitschrift f�r angewandte Mathematik und Physik, 1987
Boundary value problems of the type \[ (*)\quad \Delta w(x)+f(w(x),\lambda)=0,\quad x\in \Omega;\quad w(x)=0,\quad x\in \partial \Omega, \] are considered, where \(f: {\mathbb{R}}\times {\mathbb{R}}\to {\mathbb{R}}\) is a smooth function, \(\Omega =\{x\in {\mathbb{R}}^ n\); \(\| x\| 0\) for all \(x\in \Omega\) then \(w_ 0\) is spherically symmetric.
