设A和B为希尔伯特空间上的无界自伴算子,若存在稠密线性子空间D⊆D(AB)∩D(BA),使得对任意x∈D有ABx=BAx,本文从域相等的角度给出了A与B强交换性的若干刻画。
英文摘要
Let $A$ and $B$ be unbounded self-adjoint operators on a Hilbert space. Suppose that there exists a dense linear subspace $D\subseteq D(AB)\cap D(BA)$ such that $ABx=BAx$ for $x \in D$. We give some characterizations of the strong commutativity of $A$ and $B$ in terms of domain equalities.
