A remark on the essential self-adjointness for Klein-Gordon type operators
arXiv:2202.13499 · doi:10.1007/s00023-023-01277-2
Abstract
Here we discuss a new simplified proof of the essential self-adjointness for formally self-adjoint differential operators of real principal type, previously proved by Vasy (2020) and Nakamura-Taira (2021). For simplicity, here we discuss the second order cases, i.e., Klein-Gordon type operators only.
