MULTIPLE POSITIVE SOLUTIONS AND BIFURCATION FOR AN EQUATION RELATED TO CHOQUARD’S EQUATION [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 2003
AbstractIn this paper we study the existence of multiple positive solutions and the bifurcation problem for the following equation:$$ -\Delta u+u=\biggl(\int_{\mathbb{R}^3}\frac{|u(y)|^2}{|x-y|}\,\mathrm{d}y\biggr)u+\mu f(x),\quad x\in\mathbb{R}^3, $$where $f(x)\in H^{-1}(\mathbb{R}^3)$, $f(x)\geq0$, $f(x)\not\equiv0$.

Regularity and Classification of Solutions to Fractional‐Order Systems With Hartree‐Type Nonlinearities

open access: yesAbstract and Applied Analysis, Volume 2025, Issue 1, 2025.
This paper is concerned with the positive solutions to a fractional‐order system with Hartree‐type nonlinearity and its equivalent integral system. We firstly use the regularity lifting lemma to obtain the integrability and smoothness of the solutions.

Existence of stable standing waves for the Schrödinger–Choquard equation

open access: yesBoundary Value Problems, 2018
In this paper, by variational methods and the profile decomposition of bounded sequences in H1 $H^{1}$ we study the existence of stable standing waves for the Schrödinger–Choquard equation with an L2 $L^{2}$-critical nonlinearity. Our results extend some
