This is the website of the topology seminar at Northeastern University, organized by Ben Knudsen, Jose Perea, and Alex Suciu. The scope of the seminar encompasses algebraic, geometric, combinatorial, and applied topology. The seminar meets on Tuesdays at 12pm Boston time unless otherwise noted. Talks marked “hybrid” occur in Lake Hall 509 and stream live (Zoom meeting 975 7713 9071, password “topology”), while talks marked “fully remote” occur over Zoom (same information). Please email Ben if you’d like to be added to the mailing list.
