Some Reverse Hardy-Littlewood-Sobolev Type Inequalities
Qianqiao Guo, Zhe Pu, Jiankang Xia
We establish some sharp reverse Hardy-Littlewood-Sobolev (HLS) type inequalities on \(\mathbb{R}^n\) and \(\mathbb{R}_+^n\). Using an operator representation, we overcome the diffi…
Normalized groundstates for mixed -Laplacian equations in with exponential critical growth
Jiankang Xia, Chao Zhong
We investigate normalized groundstates for mixed -Laplacian equations \begin{align*} \begin{cases} -Δ_p u-Δu+λu=f(u) & \text{in } \mathbb{R}^2, \displaystyle \int_{\mathbb{R…
Saddle solutions for the Choquard equation with a general nonlinearity
Jiankang Xia
In the spirit of Berestycki and Lions, we prove the existence of saddle type nodal solutions for the Choquard equation \[ -Δu + u= \big(I_α\ast F(u)\big)F'(u)\qquad \text{ in }\;\m…
Saddle solutions for the fractional Choquard equation
Yin-Xin Cui, Jiankang Xia
We study the saddle solutions for the fractional Choquard equation \begin{align*} (-Δ)^{s}u+ u=(K_α\ast|u|^{p})|u|^{p-2}u, \quad x\in \mathbb{R}^N \end{align*} where , $…

Jean Van Schaftingen, Jiankang Xia
We prove the existence of ground state solutions by variational methods to the nonlinear Choquard equations with a nonlinear perturbation \[ -Δu+ u=\big(I_α*|u|^{\fracα{N}+1}\big)|…
