Mathematical Sciences: NSF-CBMS Regional Conference in the Mathematical Sciences on Discrete Groups, Expanding Graphs and Invariant Measures; Norman, OK; May, 1989

年希伯来大学的亚历山大卢博茨基教授 耶路撒冷将在一个国家科学基金会-CBMS区域首席讲师 会议将于年在诺曼的俄克拉荷马州大学举行 1989年5月 这些讲座将探讨 图论和群论，特别是 构造扩展图的序列，这也关系到 测量理论和开关网络的设计。

Professor Alexander Lubotzsky of the Hebrew University in Jerusalem will be principal lecturer at an NSF-CBMS Regional Conference to be held at the University of Oklahoma in Norman in May of 1989. The lectures will treat the connection between graph theory and group theory, particularly problems of constructing sequences of expanding graphs, which also bears on measure theory and the design of switching networks.
