Conference Travel: Automorphisms of Free Groups: Algorithms, Geometry and Dynamics

2012年秋季将在西班牙巴塞罗那的Recerca matemàtica(CRM)举办一个为期一学期的特别课程，名为“自由团体：算法、几何和动力学”。将有两个重点活动，(1)主要针对研究生和博士后的一系列高级课程，暂定于9月17日至21日的一周举行；(2)暂定于11月26日至30日的一周举行的国际会议。最近围绕自由群的外自同构群有一系列的活动。在这一激动人心的发展时期，高级课程的目的将是吸引未来的研究人员，并为他们参加随后的国际会议做好准备。博士后和更高级的研究生也将被邀请介绍他们自己的工作。这次国际会议将汇集许多顶尖的专家，主要来自北美和欧洲，就他们的研究发表演讲，分享想法，并发起新的项目。人类自然会被对称所吸引，无论是蜂巢中的规则六角形图案，还是诗歌中巧妙的押韵方案，还是阿尔罕布拉美丽的瓷砖。当我们第一次遇到某种东西并试图理解它时，对象的对称性通常是我们寻找的第一个性质。群是数学家S定义和思考对称性的方法。正如深入研究整数对于理解有理数是重要的，因为每个有理数都是两个整数的商，深入研究自由群对于理解群是重要的，因为每个群都是两个自由群的商。自由基团的对称性是本次国际会议的焦点，也是高级课程的重点。顶尖的数学家将出席会议，讨论这一领域的当前进展，并培训年轻的研究人员。高级课程的讲师将准备好装订好的笔记，然后出版。欲了解更多信息，请访问客户关系管理http://www.crm.es的网站和会议网站http://www.crm.es/Activitats/Activitats/2012-2013/Automorphisms/default.htm。

During Fall 2012 there will be a semester-long special program entitled "Free Groups: Algorithms, Geometry and Dynamics" held at the Centre de Recerca Matemàtica (CRM) in Barcelona, Spain. There will be two focused events, (1) a series of advanced courses primarily aimed at graduate students and postdocs tentatively set for the week of September 17-21 and (2) an international conference tentatively set for the week of November 26-30. There has been lately a flurry of activity surrounding the group of outer automorphisms of a free group. During this exciting time in its development, the advanced courses will be aimed to attract future researchers, and to prepare them to attend the subsequent international conference. Postdocs and more advanced graduate students will also be invited to give presentations on their own work. The international conference will bring together many of the top experts, primarily from North America and Europe, to give talks on their research, to share ideas, and to initiate new projects.Humans are naturally attracted to symmetry, be it a regular hexagonal pattern in a honeycomb, a clever rhyme scheme of a poem or the beautiful tilings in the Alhambra. The symmetries of an object are often the first properties we look for when we encounter something for the first time and try to understand it. A group is a mathematician?s way of defining and thinking about symmetry. Just as a thorough investigation of the integers is important to understand the rational numbers because every rational number is the quotient of two integers, a thorough investigation of free groups is important to understand groups because every group is the quotient of two free groups. Symmetries of free groups are the focus of this international conference and the of advanced courses. Leading mathematicians will be at the conference to discuss current progress in this area and to train younger researchers. Instructors for the advanced courses will prepare notes that will be bounded and subsequently published.
