Normalized solutions for the NLS equation with mixed fractional Laplacians and combined nonlinearities

Shubin Yu, Chen Yang, Chun-Lei Tang

We look for normalized solutions to the nonlinear Schrödinger equation with mixed fractional Laplacians and combined nonlinearities $$ \left\{\begin{array}{ll} (-Δ)^{s_{1}} u+(-Δ)^…
