Multiple tubular excisions and large Steklov eigenvalues

Jade Brisson

Given a closed Riemannian manifold $M$ and $b \geq 2$ closed connected submanifolds $N_{j} \subset M$ of codimension at least $2$ , we prove that the first non-zero eigenvalue of the dom…

Tubular excision and Steklov eigenvalues

Jade Brisson

Given a closed manifold $M$ and a closed connected submanifold $N \subset M$ of positive codimension, we study the Steklov spectrum of the domain $Ω_{ε} \subset M$ obtained b…
