Representation Theory and applications to Combinatorics, Geometry and Quantum Physics

“组合数学、几何和量子物理的表示理论和应用”会议将于2013年12月13日至19日在俄罗斯莫斯科独立大学举行。这将是顶尖数学家和年轻学者的一次重大聚会，他们的工作符合表示理论的领域。会议范围广泛，旨在介绍该领域一些最重要的最新发展和技术，特别是近年来出现并极大地促进了这些领域的每个领域的丰富的表示理论、组合学、几何和物理之间的互连网络。会议的主题包括代数群、几何表示理论、顶点代数、无限维李代数、平面划分的组合学、保形场理论和计数代数几何。许多讲座将涉及表示理论在数学物理、组合学和代数几何中的应用。组织者预计这次会议将是这些领域的研究人员的一次重大聚会，也是过去几年在莫斯科举行的最重要的数学活动之一。我们预计它将吸引许多研究生和博士后研究员，特别是来自美国的研究生和博士后研究员。在描述小物体(如原子、电子、原子核等)的世界的量子物理学中，物理系统的状态是随机的，不像经典物理学那样是确定的。换句话说，状态不再是经典状态空间的确定点，而是系统位置空间的函数，其平方大小表示系统在该特定状态下被发现的机会。这样的函数可以用数字相加和相乘，也就是说，它们形成了所谓的线性空间。系统的对称性通过该空间的线性变换起作用，因此在研究量子系统中起着重要的作用。数学中研究对称在线性空间中的作用的部分称为表示论，因为我们用线性变换来表示对称。因此，表象理论在量子物理和其他物理领域中非常有用，而物理学反过来又不断地提供对表象理论和其他数学领域的深刻见解。例如，近年来，源于量子场论的无限维对称表示理论的发展一直是一个活跃的研究领域。在会议期间，主要的数学家和数学物理学家，其中许多来自美国，将讨论表示理论与数学相关领域之间的联系，以及与物理的联系，特别是鉴于最近的突破。对于将参加会议的年轻数学家和研究生来说，会议将是非常有用的。这笔奖金将用于支付美国演讲者和参与者的旅费和当地费用。会议材料将通过会议网站http://bogomolov-lab.ru/rep2013/，传播，这将使美国和世界各地的广大观众能够访问在会议上提出的想法。来自该奖项的NSF支持将在网站上发布广告，美国的参与者将能够申请这一支持。

The conference 'Representation Theory and Applications to Combinatorics, Geometry and Quantum Physics' will be held on December 13 through 19, 2013, at the Independent University of Moscow in Russia. It will be a major gathering of the leading mathematicians and young scholars whose work fits in the realm of representation theory. The conference has a broad scope and it aims to present some of the most important recent developments and techniques in this field, in particular the rich web of interconnections between representation theory, combinatorics, geometry, and physics, which has emerged in recent years and has greatly helped to advance each of these fields. The topics to be covered in the conference include algebraic groups, geometric representation theory, vertex algebras, infinite dimensional Lie algebras, combinatorics of plane partitions, conformal field theory and enumerative algebraic geometry. Many talks will involve applications of representation theory to mathematical physics, combinatorics and algebraic geometry. The organizers expect the conference to be a major gathering of researchers in these fields and one of the most important mathematical events to take place in Moscow in the last few years. We expect that it will attract many graduate students and postdoctoral fellows, especially from the USA.In quantum physics, which describes the world of small objects (such as atoms, electrons, nuclei, etc) the state of a physical system is random and not definitively determined, unlike classical physics. In other words, states are no longer definite points of the classical space of states, but rather functions on the space of positions of the system, whose squared magnitude represents the chance the system will be found in that particular state. Such functions can be added and multiplied by numbers; that is, they form what is called a linear space. Symmetries of the system act by linear transformations of this space and therefore play an important role in studying quantum systems. The part of mathematics which studies actions of symmetries in linear spaces is called representation theory since we represent symmetries by linear transformations. Representation theory is thus extremely useful in quantum physics and other areas of physics, while physics, in turn, constantly provides deep insights into representation theory and other areas of mathematics. For example, in recent years the development of the representation theory of infinite-dimensional symmetries, coming from quantum field theory, has been an active area of research. During the conference leading mathematicians and mathematical physicists, many from the United States, will discuss the connections between representation theory and related fields in mathematics, as well as the connections to physics, especially in light of recent breakthroughs. The conference will be very useful for young mathematicians and graduate students who will attend the conference. The money from this award will support the travel and local expenses of US-based speakers and participants. Conference materials will be disseminated through the conference website http://bogomolov-lab.ru/rep2013/, which will allow the ideas presented at the conference to be accessed by a wide audience in the US and around the world. NSF support from this award will be advertised on the website, and US-based participants will be able to apply for this support.
