On the simplicity of the sloshing eigenvalues
Abstract
This paper investigates sloshing problems defined by $-Δu=0$ in $Ω$, with mixed boundary conditions: $\partial_νu=λu$ on $S$, and either $\partial_νu=0$ or $u=0$ on $W$. Here, $Ω$ represents a smooth bounded domain in $\mathbb{R}^n$ with boundary $\partialΩ=S \cup W$. We demonstrate that under small domain perturbations, all resulting eigenvalues are simple.
