Cascade Topology Seminar

级联拓扑研讨会在赠款期间的首次会议发生在2016年11月19日至20日的周末在西雅图大学，位于华盛顿的西雅图。 该研讨会计划在整个赠款期间继续每半年在美国太平洋西北部和加拿大西南部的各大学举行一次会议。 该研讨会提供了在类似领域的工人之间的频繁接触，允许从业人员通过引入来自该地区以外的演讲者和专家来了解最新发展，使太平洋西北部和加拿大西南部的本科生和研究生，博士后，大学教师和工业拓扑学家能够听取，咨询，并与外部演讲者和其他机构的从业人员合作，除了为学术界，工业界和政府的本地从业人员提供机会，介绍他们的工作外， 由于级联拓扑研讨会的部分目的是让其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，各种组织者的利益往往反映了利益的主持人，因此，在研讨会上的介绍通常涉及代数，几何，或低维拓扑，微分或代数几何，或组合群论。 研讨会还与西北太平洋几何研讨会和西部各州几何拓扑讲习班协调活动，偶尔与它们举行联席会议。研讨会演讲中涵盖的最新主题包括三角剖分，扭曲结和均匀厚度属性，直角Coxeter多面体，双曲6-流形，结空间中同源类的几何代表，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，大体积和谱隙流形上的度量，性质的亚历山大多项式和纽结弗洛尔同调，高真实的K-理论的频谱，bo-Adams谱序列，单纯EHP序列在A1代数拓扑，Calabi-Yau范畴，弗洛尔理论的余切丛，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举行的研讨会会议的链接，请访问：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.
