这个项目是关于算子代数理论的数学研究。这些对象出现在量子力学的某些公式中,它们(或者更确切地说,它们的自伴随部分)代表被建模系统的可观测对象。这一领域的基本构造之一是由给定代数上的群作用形成交叉积。(在物理学中,这个群很可能是实数,通过时间转换作用于可观测的代数,从而给出系统的动力学。)最近,一种叫做交叉副积的对偶结构被证明是非常有用的,特别是当所讨论的群是非abel的时候。Gootman教授将继续他对交叉积和余积的研究,特别是通过使用非交换对偶理论、非阿贝尔调和分析和表示理论来研究这些代数的各种性质(理想结构、对偶拓扑、类型等)。
英文摘要
This project is mathematical research in the theory of operator algebras. These objects turn up in some formulations of quantum mechanics, where they (or rather their selfadjoint part) represent the observables of the system being modeled. One of the basic constructions in this area is the formation of the crossed product from a group action on a given algebra. (In physics, the group would most likely be the real numbers, acting on the algebra of observables by time translation to give the dynamics of the system.) Recently, a dual construction called the crossed coproduct has turned out to be very useful, especially when the group in question is nonabelian. Professor Gootman will continue his investigations of crossed products and coproducts, particularly with an eye to studying various properties of these algebras (ideal structure, dual topology, type, etc.) by interrelating the use of non- commutative duality theory, non-abelian harmonic analysis, and representation theory.
