Concentration Phenomena of Normalized Solutions of Critical Biharmonic Equations with Combined Nonlinearities in ${\mathbb{R}}^N$

Yueqiang Song, Jiaying Ma, Dušan D. Repovš

We prove the multiplicity and concentration of normalized solutions of critical biharmonic equations with combined nonlinearities in ${\mathbb{R}}^N$ \begin{equation*} Δ^{2}u+V(\v…
