Normalized solutions for a class of fractional Choquard equations with the HLS lower critical term and a nonlocal perturbation
Shaoxiong Chen, Vishvesh Kumar, Zhipeng Yang +1
In this paper, we study the mass-constrained fractional Choquard equation \( (-Δ)^s u = λu + α(I_μ* |u|^{\frac{2N-μ}{N}})|u|^{\frac{2N-μ}{N}-2}u + (I_μ* |u|^p)|u|^{p-2}u \) in \( \…
Multiple standing waves of Helmholtz equation with mixed dispersion concentrating in the high frequency limit
Shaoxiong Chen, Fei Yuan, Fukun Zhao +1
In this paper, we study the nonlinear Helmholtz equation with mixed dispersion \begin{equation*} Δ^2 u-βk^2\, Δu+αk^4 u=W(x)\, |u|^{p-2}u~\text{in}~\mathbb{R}^N, \end{equation*} wh…
Existence and concentration of ground state solutions for an exponentially critical Choquard equation involving mixed local-nonlocal operators
Shaoxiong Chen, Min Yang, Zhipeng Yang
We study the Choquard equation involving mixed local and nonlocal operators \[-\varepsilon^{2}Δu+\varepsilon^{2s}(-Δ)^{s}u+V(x)u=\varepsilon^{μ-2}\left(\frac{1}{|x|^μ}*F(u)\right)f…
