Topology Reading Seminar
by Schirmer, Trent 28 Aug '14

28 Aug '14

Hi Everyone, For everyone who's interested, we will be having a topology reading seminar on Thursdays, 11:00-12:00 in room 405. The paper is Kirby and Gay's "Trisections of 4-manifolds" which I've attached. The proof of their main result relies heavily on the use of Morse 2 functions, which are interesting in their own way. I've attached their paper on Morse 2-functions as well for anyone who's interested, although you don't need to know anything about them to understand the results of "Trisections..." I'll give the first presentation next week. Best, Trent

Dear colleagues, The folks at Arkansas are thinking of having the Fall Redbud conference on either October 4 or November 1. If you have a preference, would you please email me soon so that I can get back to them? If you know anybody who would like to attend but is not on the mdtop list, please ask them, too. Thanks very much! Sean

Topology Seminar
by Schirmer, Trent 26 Aug '14

26 Aug '14

Hi Everyone, Since no one has sent out any e-mails about the topology seminar this semester I'm volunteering myself to organize it, although if anyone else wants to run it I'm totally fine with that! If it works for everyone we should have an organizational meeting this Thursday at 3:30 PM. If that doesn't work for someone please let me know. Also I would like to have a reading seminar, so please come ready with ideas for that. Personally I'm interested in some recent work by Rob Kirby and David Gay (and related work by Alex Zupan and others) about trisections of 4-manifolds, as it relates the theory of Heegaard splittings to 4-manifold topology in an interesting new way. Best, Trent
