Exponential localization of Steklov eigenfunctions on warped product manifolds: the flea on the elephant phenomenon

Thierry Daudé, Bernard Helffer, François Nicoleau

This paper is devoted to the analysis of Steklov eigenvalues and Steklov eigenfunctions on a class of warped product Riemannian manifolds $(M,g)$ whose boundary $\partial M$ consis…
