[Binghamton Geometry/Topology Seminar] Adam Saltz (University of Georgia)

Dear seminar people,

Thursday we will have lunch in the Chenango Room (meet at noon at the math
office window), and dinner at 6. I am happy to drive people from campus,
then drop off at home. It would reflect well on the department if there
were at least one faculty member other than the organizer at dinner.

Title:
Pictorial link homology (and Floer homology?)

Abstract:
First, I'll describe Bar-Natan's amazing reformulation of Khovanov
homology using diagrams and cobordisms (and a bit of category theory)
rather than linear algebra. This will be totally accessible to graduate
students!

Then I'll tell you about a strategy to show that link cobordisms induce
well-defined maps on "Khovanov-Floer theories" (Floer homology theories
which admit spectral sequences from Khovanov homology). This strengthens a
result of Baldwin, Hedden, and Lobb. I also think it's a good start on
parametrizing these theories, and I'll tell you how.
