Algebra Seminar: Beliakova -- Quantized annular Khovanov homology

IMPORTANT: If Carslaw building is still closed, we will have the seminar at the usual
time 12-1 in 

Abercrombie Building ABS Seminar Room 2020. 

It is a 10 minute walk from Carslaw down Butlin Ave and Cordrington St, 
see https://goo.gl/maps/1S9so7UFUZ32. 


Speaker: Anna Beliakova (University of Zurich) 

Date: Friday 30 November, 12-1pm 

Place: Carslaw 375 

Title: Quantized annular Khovanov homology 

Abstrac: In the talk I will explain how one can quantize the annular Khovanov homology
to get a new triply graded homology theory for annular links which is strictly
functorial with respect to annular cobordisms.  This theory carries the action of the
quantum sl(2) intertwining the action by cobordisms and provides non-trivial invariants
of 2-knots.  Moreover, in the quantized annular setting the infinite Cooper-Krushkal
complex categorifing the Jones-Wenzl projector becomes finite and homotopic to the
Khovanov complex for the colored Jones.  Joint work with M. Hogancamp, K. Putyra and
S. Wehrli.
