有界扰动下巴拿赫空间上多个半群生成元的Bernstein函数。II

Bernstein functions of several semigroup generators on Banach spaces under bounded perturbations. II

A. R. Mirotin

摘要:

本文研究多维Bochner-Phillips谓词演算。在作者的前一篇文章中,考虑了巴拿赫空间上几个交换半群生成元的Bernstein函数的有界扰动,证明了这类函数的Lipschitz性条件和算子范数的估计。在一维情形下,证明了巴拿赫空间上半群生成元的Bernstein函数的Frechet可微性,并导出了Livschits-Kreenn迹公式的推广.本文的目的是证明多维情形下算子Bernstein函数的Frechet可微性和Livschits-Krestern迹公式。

英文摘要:

The paper deals with multidimensional Bochner-Phillips functional calculus. In the previous paper by the author bounded perturbations of Bernstein functions of several commuting semigroup generators on Banach spaces where considered, conditions for Lipschitzness and estimates for the norm of commutators of such functions where proved. Also in the one-dimensional case the Frechet differentiability of Bernstein functions of semigroup generators on Banach spaces where proved and a generalization of Livschits-Kreĭn trace formula derived. The aim of the present paper is to prove the Frechet differentiability of operator Bernstein functions and the Livschits-Kreĭn trace formula in the multidimensional setting.
