Existence of Multiple Positive Solutions for Choquard Equation with Perturbation [PDF]
This paper is concerned with the following Choquard equation with perturbation: -Δu+V(x)u=(1/|x|α∗|u|p)|u|p-2u+g(x), u∈H1(RN), where N≥3, α∈(0,N), and 2-(α/N)

The Choquard Equation with Weighted Terms and Sobolev-Hardy Exponent
We study a nonlinear Choquard equation with weighted terms and critical Sobolev-Hardy exponent. We apply variational methods and Lusternik-Schnirelmann category to prove the multiple positive solutions for this problem.

Nodal solutions for the Choquard equation [PDF]
We consider the general Choquard equations −Δu+u=(Iα∗|u|^p)|u|^(p−2)u where Iα is a Riesz potential. We construct minimal action odd solutions for p∈((N+α)/N,(N+α)/(N−2)) and minimal action nodal solutions for p∈(2,(N+α)/(N−2)).

On Uniqueness for the Generalized Choquard Equation
We consider the generalized Choquard equation describing trapped electron gas in three dimensional case. The study of orbital stability of the energy minimizers (known as ground states) depends essentially in the local uniqueness of these minimizers. The

The logarithmic Choquard equation : sharp asymptotics and nondegeneracy of the groundstate [PDF]
We derive the asymptotic decay of the unique positive, radially symmetric solution to the logarithmic Choquard equation −∆u + au = 1 2π ln 1 |x| * |u| 2 u in R 2 and we establish its nondegeneracy.

Soliton dynamics for the generalized Choquard equation
We investigate the soliton dynamics for a class of nonlinear Schrödinger equations with a non-local nonlinear term. In particular, we consider what we call generalized Choquard equation where the nonlinear term is $(|x|^{\theta-N} \star |u|^p) |u|^{p-2}
