Mathematical Sciences: Special Year in Ergodic Theory and Dynamical Systems

这笔赠款将资助1991年在北卡罗来纳大学教堂山分校举行的遍历理论和动力系统特别年。特别年期间的研究活动将集中在可数状态马尔可夫位移、异常遍历定理和轨道等价概念的问题上。计划举办三个讲习班，将这些领域的专家聚集在一起进行短期的密集活动。我们还将讨论光滑动力学和遍历理论中有趣的应用和相关问题。数学系正在资助三个访问职位，这笔拨款将用于支付一系列短期访问者和研讨会参与者的部分费用。

This grant will fund a special year in Ergodic Theory and Dynamical Systems to be held at the University of North Carolina at Chapel Hill during the calendar year 1991. Research activity during the Special Year will concentrate on problems in countable state Markov shifts, unusual ergodic theorems, and notions of orbit equivalence. Three workshops are planned to bring together experts in each of these areas for a short period of intense activity. Interesting applications and related problems in smooth dynamics and ergodic theory will also be discussed. The Department of Mathematics is funding three visiting positions and this grant will fund partial expenses for a series of short term visitors and workshop participants.
