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

2013年7月1日至5日，在法国马赛Luminy的国际数学会议中心（Centre International de Rencontres Mathematiques）将举行题为“低维拓扑、结点和可序群”的会议。会议的目的是探索拓扑和群的有序性之间的联系，特别是在三维流形和结理论的背景下。会议将在戴尔·罗尔夫森70岁生日之际荣誉他在这些领域的贡献。斯蒂芬·毕格罗、米歇尔·布瓦洛、丹尼·卡莱加里、朱利安·马尔凯、安德烈斯·纳瓦斯、彼得·奥兹瓦斯、路易莎·保卢齐、戴尔·罗尔夫森、迪伦·瑟斯顿和伯特·韦斯特将进行一个小时的会谈。此外，还将有20个半小时的讲座。三维拓扑学是研究空间的大规模结构，这些空间在局部上与我们生活的普通三维空间相似。近年来，这一主题取得了巨大的进展，特别是佩雷尔曼对庞加莱猜想的证明。在另一个方向上，上述主题之间的深刻联系开始出现，会议的目的是进一步探讨这些联系，并通过汇集来自不同领域的国际专家来鼓励思想的相互交流。它还将为来自美国的早期职业数学家提供一个与其他研究人员（包括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。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/
