Lower bounds on Steklov eigenfunctions for a class of curvilinear polygons

Jeffrey Galkowski, Ruoyu P. T. Wang

Steklov eigenfunctions, $\{{\varphi }_{{\sigma }_j}{\}}_{j=0}^{\infty }$, are the eigenfunctions of the Dirichlet to Neumann map on a bounded domain with eigenvalue ${\sigma }_j$. This paper considers Steklov e…
