Conference on low-dimensional topology, knots, and orderable groups

题为“低维拓扑、纽结和可排序群”的会议将于2013年7月1日至5日在法国马赛卢米市的国际伦孔特数学中心举行。会议的目的是探索群的拓扑学和可排序性之间的联系，特别是在三维流形和纽结理论的背景下。大会将在戴尔·罗夫森70岁生日之际向他在这些领域做出的贡献表示敬意。斯蒂芬·比格罗、米歇尔·博伊洛、丹尼·卡莱加里、朱利安·马尔凯、安德烈斯·纳瓦斯、彼得·奥兹瓦特、路易莎·保卢齐、戴尔·罗夫森、迪伦·瑟斯顿和伯特·威斯特将进行一小时的演讲。此外，还将有20个半小时的演讲。三维拓扑学研究的是局部空间的大规模结构，就像我们生活的普通三维空间一样。近年来，这一课题取得了巨大的进展，尤其是佩雷尔曼对庞加莱猜想的证明。另一方面，上述专题之间的深层联系开始出现，会议的目的是通过召集来自不同领域的国际专家，进一步探讨这些联系并鼓励思想的交流。它还将为来自美国的早期职业数学家提供一个与其他高级和初级研究人员互动的机会，并在一个刺激的环境中讨论和展示他们自己的工作。会议网站的网址是http://thales.math.uqam.ca/~rolfsenfest/

A conference entitled "Low Dimensional Topology, Knots, and Orderable Groups" will be held at the Centre International de Rencontres Mathematiques in Luminy, Marseille, France, from July 1 to 5, 2013. The aim of the conference is to explore connections between topology and orderability properties of groups, especially in the context of the theory of three-dimensional manifolds and knots. The conference will honor Dale Rolfsen's contributions to these areas on the occasion of his 70th birthday. One-hour talks will be given by Stephen Bigelow, Michel Boileau, Danny Calegari, Julien Marche, Andres Navas, Peter Ozsvath, Luisa Paoluzzi, Dale Rolfsen, Dylan Thurston, and Bert Wiest. In addition there will be twenty half-hour talks.Three-dimensional topology is the study of the large-scale structure of spaces that are locally like the ordinary three-dimensional space in which we live. The subject has seen huge advances in recent years, notably Perelman's proof of the Poincare Conjecture. In another direction, deep connections between the topics mentioned above are beginning to emerge, and the aim of the conference is to further explore these connections and encourage cross-fertilization of ideas by bringing together international experts from the different areas involved. It will also provide an opportunity for early-career mathematicians from the US to interact with other researchers, both senior and junior, and to discuss and present their own work in a stimulating environment.The url for the conference website is http://thales.math.uqam.ca/~rolfsenfest/
