Cascade Topology Seminar

在资助期间，Cascade拓扑研讨会的首次会议将于2016年11月19-20日在位于华盛顿州西雅图的西雅图大学举行。该研讨会计划在整个资助期间每半年在美国、太平洋、西北和加拿大西南部的各大学举行一次会议。研讨会为类似领域的工作者提供了频繁的联系，使从业者能够通过邀请来自该地区以外的演讲者和专家来跟上最新的发展，使加拿大西北太平洋和西南地区的本科生和研究生、博士后、大学教师和工业拓扑学家能够听取、咨询和与外部演讲者和其他机构的从业者合作。除了为当地学术界、工业界和政府的从业人员提供机会，就他们自己的工作进行演讲外。由于级联拓扑研讨会的设计部分是为了让参与者了解他们自己和相关领域的最新发展，因此没有试图限制所涵盖的主题。然而，各种组织者的兴趣往往反映在演讲者的兴趣上，因此，研讨会上的演讲通常涉及代数、几何或低维拓扑、微分或代数几何或组合群论。讨论会还与太平洋西北几何讨论会和西方国家几何拓扑学讲习班协调其活动，它们偶尔举行联席会议。最近的主题包括三角形、捻结和均匀厚度性质、直角Coxeter多边形、双曲6-流形、结点空间中同调类的几何表示、四流形拓扑、Kervaire流形中的有限群作用、局部对称空间、对称群的上同调、大体积和谱间隙流形上的度量、Alexander多项式和结花同调的性质、高实k理论谱，bo-Adams谱序列，A1代数拓扑中的简单EHP序列，Calabi-Yau范畴，共切束的Floer理论，弦拓扑。有关级联拓扑研讨会的一般信息、支持信息和应用程序以及即将召开的研讨会的链接可在以下网站找到：http://www.pdx.edu/math/cascade-topology-seminar

The initial meeting of the Cascade Topology Seminar during the grant period occurs the weekend of November 19-20, 2016 at Seattle University, located in Seattle, Washington. The Seminar is scheduled to continue meeting semi-annually throughout the grant period at various Universities in the US Pacific Northwest and Southwestern Canada. The Seminar provides for frequent contacts between workers in similar fields, allows for practitioners to keep abreast of recent developments by bringing in speakers and experts from outside the region, enables undergraduate and graduate students, post-docs, University faculty and industrial topologists in the Pacific Northwest and Southwestern Canada to hear, consult, and collaborate with the outside speakers and with practitioners from other institutions, in addition to providing an opportunities for local practitioners in academia, industry, and government to lecture on their own work. As the Cascade Topology Seminar is designed in part to keep its participants abreast of recent developments in their own and related fields, no attempt is made to limit the topics covered. However, the interests of the various organizers tend to be mirrored by the interests of the presenters, thus, the presentations at the Seminars usually concern algebraic, geometric, or low dimensional topology, differential or algebraic geometry, or combinatorial group theory. The Seminar also coordinates its activities with the Pacific Northwest Geometry Seminar and the Western States Geometric Topology Workshop with whom joint meetings have occasionally been held. Recent topics covered in Seminar presentations include triangulations, twist knots and the uniform thickness property, right-angled Coxeter polytopes, hyperbolic 6-manifolds, geometric representatives of homology classes in the space of knots , four manifold topology, finite group actions in Kervaire manifolds, locally symmetric spaces, the cohomology of symmetric groups, metrics on manifolds with large volume and spectral gap, Properties of the Alexander polynomial and knot Floer homology, higher real K-theory spectra ,the bo-Adams spectral sequence, the simplicial EHP Sequence in A1 algebraic topology, Calabi-Yau categories, the Floer theory of a cotangent bundle, and string topology.
