两个变量的跟踪公式

Trace Formula For Two Variables

Arup Chattopadhyay, Kalyan B. Sinha

摘要:

将Krein定理自然推广到可分希尔伯特空间$\mathcal{H}$中有界自伴算子的交换元组$\left(H_1^0,H_2^0\right)$和$\left(H_1,H_2\right)$,其中$H_j-H_j^0 = V_j\in \mathcal{B}_2(\mathcal{H})$($\mathcal{H}$上所有希尔伯特-施密特算子的集合)为$j=1,2,$,导致迹下的Stokes类公式。证明中的一个主要成分是交换自伴n元组算子的有限维近似结果,这是Weyl-von Neumann-Berg定理的推广。

英文摘要:

A natural generalization of Krein's theorem to a pair of commuting tuples $\left(H_1^0,H_2^0\right)$ and $\left(H_1,H_2\right)$ of bounded self-adjoint operators in a separable Hilbert space $\mathcal{H}$ with $H_j-H_j^0 = V_j\in \mathcal{B}_2(\mathcal{H})$(set of all Hilbert-Schmidt operators on $\mathcal{H}$) for $j=1,2,$ leads to a Stokes-like formula under trace. A major ingredient in the proof is the finite-dimensional approximation result for commuting self-adjoint n-tuples of operators, a generalization of Weyl-von Neumann-Berg's theorem.
