Existence of groundstates for a class of nonlinear Choquard equations in the plane
Abstract
We prove the existence of a nontrivial groundstate solution for the class of nonlinear Choquard equation $$ -Δu+u=(I_α*F(u))F'(u)\qquad\text{in }\mathbb{R}^2, $$ where $I_α$ is the Riesz potential of order $α$ on the plane $\mathbb{R}^2$ under general nontriviality, growth and subcriticality on the nonlinearity $F \in C^1 (\mathbb{R},\mathbb{R})$.
