Cascade Topology Seminar

DMS-0423910Steven A.Bleiler级联拓扑学研讨会是太平洋地区、美国西北部和加拿大西南部数学家共同努力的成果。咨询委员会以协商一致的方式决定会议地点，并作为当地组织者并与其协商。当地组织者与咨询委员会和感兴趣的各方协商，以选择发言者名单。讲师不一定要就拓扑学主题发言。由于组织者的兴趣，大多数演讲都涉及拓扑学主题，因此研讨会的名字也因此而起。通常有两到三位演讲者来自该地区以外的地区。最近在研讨会上发表的演讲包括：三维几何化，奥比福尔德定理，拓扑机器人学，密码学和辫子群，群的有限性，拓扑量子场论中的积分结构，表示变种，n-复形在2n-空间中的嵌入，纽结理论中的Skein理论和更远的主题，映射类群的量子表示，以及4-流形的自同伦等价。级联拓扑学研讨会的设计部分是为了让参与者了解自己所在领域和相关领域的最新发展，并没有试图限制讲座所涵盖的主题。然而，不同组织者的利益往往反映在演讲者的利益上。因此，这些讲座通常涉及代数、几何或低维拓扑、微分或代数几何或组合群论。研讨会还努力使太平洋西北部和加拿大西南部的研究生和拓扑学家能够倾听、咨询外部发言者和其他机构的成员，并可能与他们合作。努力满足参与者的特殊需要，并鼓励传统上任职人数不足的群体的成员参加。喀斯喀特拓扑学研讨会的组织者也做出了持续的努力，将年轻和/或女性演讲者纳入其计划，并为当地人提供机会就他们自己的工作进行演讲。

DMS-0423910Steven A. BleilerThe Cascade Topology Seminar is a cooperative effort among mathematicians in the Pacific Northwest United States and Southwestern Canada. An advisory committee works by consensus to decide meeting sites and serve as and consult with local organizers. Local organizers consult with the advisory committee and interested parties to select a list of speakers. The lecturers do not necessarily have to speak on a topological topic. Due to the interests of the organizers, most talks do touch on topological subjects, hence the title of the seminar. Typically two or three of the speakers are from outside the region. Recent presentations in the Seminar included such topics as Geometrization in dimension 3, the Orbifold Theorem, Topological Robotics, Cryptography and the Braid Group, Finiteness Properties of Groups, Integral Structures in Topological Quantum Field Theory, Representation Varieties, Embedding n-complexes into 2n-space, Skein Theory in knot theory and beyond, Quantum Representations of Mapping Class Groups, and the self homotopy equivalences of 4-manifolds. The Cascade Topology Seminar is designed in part to keep its participants abreast of recent developments in their own and related fields, and no attempt is made to limit the topics covered in the lectures. However, the interests of the various organizers tend to be mirrored by the interests of the speakers. The lectures therefore usually concern algebraic, geometric, or low dimensional topology, differential or algebraic geometry, or combinatorial group theory. The Seminar also strives to enable graduate students and topologists in the Pacific Northwest and Southwestern Canada to hear, consult, and possibly collaborate with the outside speakers and members of other institutions. Efforts are made to accommodate special needs of participants and to encourage members of traditionally under-represented groups to participate. The Cascade Topology Seminar organizers also make a consistent effort to include younger and/or women speakers in its programs and to provide opportunities for local people to lecture on their own work.
