完全正半群的积系、子积系与扩张理论

Product systems, subproduct systems and dilation theory of completely positive semigroups

Orr Shalit

摘要:

本文致力于发展完全正映射半群的扩张理论。第一部分处理两个参数半群,也包含贡献膨胀理论的产品系统表示。第二部分研究由相当一般的半群参数化的完全正半群,主要的技术工具是子积系及其表示。第三部分研究了子积系统,以及由此产生的多变量算子理论和算子代数。

英文摘要:

This thesis is dedicated to developing a dilation theory for semigroups of completely positive maps. The first part treats two-parameter semigroups, and contains also contributions to dilation theory of product system representations. The second part deals with completely positive semigroups parameterized by quite general semigroups, where the major technical tool introduced is subproduct systems and their representations. In the third part subproduct systems are studied, together with the multivariable operator theory and operator algebras they give rise to.
