The PI will study interactions between operator algebras and conformalfield theories which have proved to be very fruitful lately. The mainemphasis of this research is placed on the study of certain representation theory questions such as Kac-Wakimoto conjecture, orbifolds and boundary states in conformal field theories using operator algebraic techniques. The applications of these operator algebraic techniqueswill lead to proofs of representation theory questionsand shed lights on exotic subfactors such as those coming from conformal inclusions. The theory of operator algebras was introduced by John von Neumann in order to provide a proper mathematical framework for Quantum Mechanics. Conformal field theory was a theory describing critical phenomena incondensed matter physics, and it also plays an important role in string theory. The remarkable interactions between operator algebrasand conformal field theory has led to many interesting mathematicalissues. The aim of this researchis to find solutions to some of the important mathematical issues that surface in this context which have a wide range of applications.

PI将研究操作员代数与保形理论之间的相互作用，这些理论最近被证明是非常富有成果的。这项研究的主要重视是对某些表示理论问题的研究，例如使用操作员代数技术中的共形领域理论中的Kac-Wakimoto猜想，Orbifolds和边界状态。这些操作员代数技术的应用将导致表示理论的证据问题和奇异子因子（例如来自保形夹杂物的）的灯光。约翰·冯·诺伊曼（John von Neumann）引入了操作者代数理论，以便为量子力学提供适当的数学框架。共形场理论是一种描述批判现象构成物理物理学的理论，它在弦理论中也起着重要作用。操作员代数共同场理论之间的显着相互作用导致了许多有趣的数学评价。 这项研究的目的是为在这种情况下浮出水面的一些重要数学问题找到解决方案。
