变形无界算子的自伴性

Self-Adjointness of Deformed Unbounded Operators

Albert Much

摘要:

我们考虑无界算子的变形,使用新的构造工具的翘曲卷积。利用Kato-Rellich定理证明了无界自伴变形算子是自伴的,如果它们满足一定的条件。这个条件证明了它本身对于振荡积分的良好定义是必要的。此外,在量子力学和量子场论的背景下,对变形无界算子的自伴性给出了不同的证明。

英文摘要:

We consider deformations of unbounded operators by using the novel construction tool of warped convolutions. By using the Kato-Rellich theorem we show that unbounded self-adjoint deformed operators are self-adjoint if they satisfy a certain condition. This condition proves itself to be necessary for the oscillatory integral to be well-defined. Moreover, different proofs are given for self-adjointness of deformed unbounded operators in the context of quantum mechanics and quantum field theory.
