Mathematical Sciences: Cascade Topology Seminar

级联拓扑研讨会是自1987年以来每年举行的一系列为期两天的会议。30至50名参与者在该地区的一个机构会面。通常周六有两到三节课，周日有一到两节课，另外还有很多非正式的讨论，春季和秋季各有一个周末。组织者吸引了优秀的演讲者，研讨会在促进该国这一地区的拓扑研究方面发挥了重要作用。这个数额不大的奖项将在未来三年内帮助组织者，主要是从太平洋西北地区以外的地区引进高质量的演讲者。

The Cascade Topology Seminar is a series of two-day meetings held each year since 1987. Thirty to fifty participants meet at an institution in the region. There are usually two or three lectures on Saturday and one or two lectures on Sunday, plus much informal discussion, on a weekend in the spring and another in the fall. The organizers have attracted excellent speakers, and the seminars have played a significant role in fostering topological research in this region of the country. This modest award will assist the organizers, mainly to bring in high quality speakers from outside the Pacific Northwest, during the next three years.
