Abstract for Lie Groups, Representations and Discrete Mathematics ConferenceFebruary 6-10, 2006The conference is part of a year-long program at the Institute for Advanced Study in Princeton, New Jersey on Lie Groups, Representations and Discrete Mathematics. The last two decades show some deep and surprising connections between questions and results in number theory in general, automorphic forms in particular and seemingly unrelated problems in discrete mathematics and computer science. These developments led to the constructions of Ramanujan graphs and complexes and to the solution of several long-standing problems. Many of these questions are related to the notion of expanders. This is a basic concept in combinatorics and computer science which found its way to the representation theory and the theory of discrete subgroups of Lie groups. Recently, it also found its use in 3-dimensional hyperbolic geometry.The goal of the conference is to bring together experts from these quite different areas of mathematics and computer science to present their work and to strengthen the potential cooperation between these scientists who usually do not meet or attend the same conferences.

李群、表示和离散数学会议摘要2006 年 2 月 6-10 日该会议是新泽西州普林斯顿高级研究所为期一年的李群、表示和离散数学项目的一部分。 过去二十年显示了一般数论中的问题和结果、特别是自同构形式以及离散数学和计算机科学中看似不相关的问题之间的一些深刻且令人惊讶的联系。 这些发展导致了拉马努金图和复合体的构建，并解决了几个长期存在的问题。 其中许多问题都与扩展器的概念有关。 这是组合学和计算机科学中的一个基本概念，它为表示论和李群的离散子群理论提供了途径。 最近，它还发现了它在 3 维双曲几何中的用途。会议的目标是将来自数学和计算机科学这些截然不同领域的专家聚集在一起，展示他们的工作，并加强这些通常从事研究工作的科学家之间的潜在合作。不见面或参加相同的会议。
