Cascade Topology Seminar

DMS-0423910 Steven A. BleilerThe Cascade Topology Seminar是美国太平洋西北部和加拿大西南部数学家的合作项目。一个咨询委员会以协商一致的方式决定会议地点，充当当地组织者并与之协商。当地组织者与咨询委员会和有关各方协商，以选择发言者名单。讲师不一定要讲拓扑主题。由于组织者的兴趣，大多数讲座确实涉及拓扑主题，因此研讨会的名称。通常有两三个发言者来自该地区以外。最近在研讨会上发表的专题包括三维几何化、轨道定理、拓扑机器人学、密码学和辫子群、群的连续性、拓扑量子场论中的积分结构、表示变体、将n-复形嵌入2n-空间、纽结理论及其以外的绞链理论、映射类群的量子表示、和4-流形的自同伦等价。级联拓扑研讨会的部分目的是让其参与者在自己的领域和相关领域的最新发展，并没有试图限制讲座中所涵盖的主题。然而，各种组织者的利益往往反映在发言者的利益上。因此，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。研讨会还努力使研究生和拓扑学家在太平洋西北部和加拿大西南部听到，咨询，并可能与外部扬声器和其他机构的成员合作。努力满足参与者的特殊需要，并鼓励传统上代表性不足的群体成员参与。级联拓扑学研讨会的组织者还不断努力，将年轻人和/或妇女发言者纳入其方案，并为当地人提供机会，介绍他们自己的工作。

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.
