Normalized solutions to mixed dispersion nonlinear Schrödinger system with coupled nonlinearity

Zhen-Feng Jin, Guotao Wang, Weimin Zhang

In this paper, we consider the existence of normalized solutions for the following biharmonic nonlinear Schrödinger system \begin{equation*} \begin{cases} Δ^2u+α_{1}Δu+λu=βr_…
