Viscosity limits for 0th order pseudodifferential operators
Jeffrey Galkowski, Maciej Zworski
Motivated by the work of Colin de Verdière and Saint-Raymond on spectral theory 0th order pseudodifferential operators on tori we consider viscosity limits in which 0th order opera…

Domains without dense Steklov nodal sets
Oscar Bruno, Jeffrey Galkowski
This article concerns the asymptotic geometric character of the nodal set of the eigenfunctions of the Steklov eigenvalue problem $$ -Δϕ_{σ_j}=0,\quad\text{ on }Ω,\qquad\qquad \par…

Eigenfunction concentration via geodesic beams
Yaiza Canzani, Jeffrey Galkowski
In this article we develop new techniques for studying concentration of Laplace eigenfunctions as their frequency, , grows. The method consists of controlling by…
