International Conference on Groups and Semigroups

“集团和半集团问题国际会议”将于2013年6月11日至14日在以色列巴伊兰大学举行。这次会议的目的是促进群论家和半群理论家之间的合作研究，他们正在使用几何、组合和动力学方面的相关技术。近年来，群论和半群论的研究方兴未艾，许多新的工具和思想将这些领域与拓扑学、几何学、动力系统、符号计算和组合学联系起来。会议将邀请这些领域的几位主要研究人员发表演讲，重点介绍使用几何、组合和动力学方法研究群和半群中的算法和渐近问题的新进展。会议记录将发表在《国际代数与计算杂志》的特刊上。群论和半群论是现代代数的核心领域，它们与包括拓扑学、几何学和形式语言理论在内的不同数学领域有着密切的联系，以及在物理和计算科学中的许多应用。群论和半群论的最新发展利用了几何学、组合学和符号动力学的各种数学工具。这次会议的目的是聚集使用这些技术的几位世界领先的专家，以促进这些领域的合作研究。来自美国、加拿大、以色列、俄罗斯和几个欧洲国家的高级研究人员将进行受邀的演讲，并将有开放的问题和讨论环节，涉及高级研究人员和初级数学家和研究生之间的互动。会议详情可在会议网站上查阅，网址为：http://www.math.vanderbilt.edu/~msapir/stuart/main.html.。

The "International Conference on Groups and Semigroups" will take place June 11-14, 2013 at Bar Ilan University in Israel. The aim of this conference is to stimulate cooperative research among group theorists and semigroup theorists who are using related techniques in the geometric, combinatorial, and dynamical aspects of the theories. Research in both group theory and semigroup theory has burgeoned in recent years, with many new tools and ideas connecting these fields to topology, geometry, dynamical systems, symbolic computation, and combinatorics. The conference will feature invited talks by several of the leading researchers in these fields, highlighting new developments using geometric, combinatorial and dynamical methods to study algorithmic and asymptotic problems in groups and semigroups. The proceedings of the conference will be published in a special issue of the International Journal of Algebra and Computation. Group theory and semigroup theory are central areas of modern algebra that have close connections with diverse areas of mathematics including topology, geometry and formal language theory, as well as many applications in the physical and computational sciences. Recent developments in group theory and semigroup theory have made use of a wide variety of mathematical tools from geometry, combinatorics and symbolic dynamics. The aim of this conference is to bring together several of the world's leading experts in the use of these techniques to stimulate cooperative research in these fields. Invited talks will be given by senior researchers from the US, Canada, Israel, Russia, and several European countries, and there will be open problem and discussion sessions involving interaction between senior researchers and junior mathematicians and graduate students.
