论文摘要
在这里，我们讨论了一个新的简化证明，证明了真实主类型的正式自我伴侣差异操作员的基本自我伴侣，此前由Vasy（2020）和Nakamura-Taira（2021）证明。为简单起见，我们在这里讨论二阶情况，即仅Klein-Gordon类型操作员。
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.
