interest in the past few decades. This article is a tour of some of the recent developments …

The Dirichlet-to-Neumann map, the boundary Laplacian, and Hörmander's rediscovered manuscript

A Girouard, M Karpukhin, M Levitin… - Journal of Spectral …, 2022 - ems.press
How close is the Dirichlet-to-Neumann (DtN) map to the square root of the corresponding
