Schroedinger算子的超弱时间算子

Ultra-Weak Time Operators of Schroedinger Operators

Asao Arai, Fumio Hiroshima

摘要:

在一个抽象的框架下,引入了时间算子的一个新概念--超弱时间算子,它是一个弱于弱时间算子的概念。建立了超弱时间算子的存在性定理。作为定理的一个应用,证明了具有势V的Schroedinger算子H在适当的条件下,包括氢原子的哈密顿量,具有超弱时间算子.此外,还得到了一类Borel可测函数$f$,使得$f(H)$具有超弱时间算子.

英文摘要:

In an abstract framework, a new concept on time operator, ultra-weak time operator, is introduced, which is a concept weaker than that of weak time operator. Theorems on the existence of an ultra-weak time operator are established. As an application of the theorems, it is shown that Schroedinger operators H with potentials V obeying suitable conditions, including the Hamiltonian of the hydrogen atom, have ultra-weak time operators. Moreover, a class of Borel measurable functions $f$ such that $f(H)$ has an ultra-weak time operator is found.
