This award funds participation by US researchers in an international research conference entitled Future Directions in Representation Theory, to be held at the University of Sydney from December 4-8, 2017. Broadly speaking, the field of representation theory deals with understanding symmetries of linear systems. The notion of "symmetries" is made precise by the mathematical concept of a group; given an abstract group, one can ask how that group can be realized via linear transformations on a vector space. This subject has algebraic origins, but current developments in representation theory involve input from other areas of mathematics, such as geometry and topology, as well as ideas from physics. This conference brings together experts from diverse research backgrounds to report on new developments and exchange ideas. Many current developments at the frontiers of representation theory rely on a diverse array of tools whose origins may be geometric, categorical, or homological in nature. Conversely, questions from representation theory have motivated a number of new developments in neighboring fields of mathematics and mathematical physics. This conference features speakers whose work lies at the interface of representation theory and these neighboring subjects, and whose research programs are indicative of the directions along which representation theory may develop in the future. Specific topics include: (i) symplectic duality and mathematical physics; (ii) categorification and categorical actions; (iii) cohomological methods in representation theory; (iv) parity sheaves and Soergel bimodules. US researchers supported by this funding will have the opportunity to interact with some of the world's leading experts in the representation theory, as well as to make contacts with peer researchers from Australia and other nations.

该奖项资助美国研究人员参加将于2017年12月4日至8日在悉尼大学举行的题为“表征理论的未来方向”的国际研究会议。广义地说，表示论的领域涉及理解线性系统的对称性。“对称性”的概念通过群的数学概念变得精确;给定一个抽象群，人们可以问这个群如何通过向量空间上的线性变换来实现。这门学科有代数的起源，但目前表示论的发展涉及到其他数学领域的输入，如几何和拓扑学，以及物理学的思想。本次会议汇集了来自不同研究背景的专家，报告新的发展和交流思想。当前表征理论前沿的许多发展依赖于各种各样的工具，这些工具的起源可能是几何的、分类的或同调的。相反，表征论的问题激发了数学和数学物理邻近领域的许多新发展。本次会议的特点发言人的工作在于接口的表征理论和这些邻近的主题，其研究计划是指示方向沿着表征理论可能在未来的发展。具体主题包括：（i）辛对偶与数学物理;（ii）范畴化与范畴作用;（iii）表示论中的上同调方法;（iv）宇称层与Soergel双模。由该基金支持的美国研究人员将有机会与一些世界领先的代表性理论专家进行互动，并与来自澳大利亚和其他国家的同行研究人员进行接触。会议网址是：https://sites.google.com/site/ausreptheory/conference2017。
