talks by Louis-Hadrien Robert on Tuesday and Thursday this week

[Mikhail Khovanov]

Dear all,

There will be two talks by Louis-Hadrien Robert (University of Geneva)
on foam evaluation and its applications to link homology. Titles and
abstracts are enclosed below.

The talks are Tuesday, Thursday 1:30pm-3pm in room 622 (Thursday room to
be confirmed).

Title (talk 1): Categorification of 1 and of the Alexander polynomial

Abstract: I will give a combinatorial and down-to-earth definition of
the symmetric gl(1) homology. It is a (non-trivial) link homology which
categorifies the trivial link invariant (equal to 1 on every link). Then
I'll explain how to use this construction to categorify the Alexander
polynomial. (joint with Emmanuel Wagner)


Title (talk 2): Foams and Soergel bimodules

Abstract: I will explain what foams are and how they can be used for
constructing link homologies. I will give different foam
evaluations. Then I will relate foams to Soergel bimodules.

Dear all,

We're changing the room for the second talk by Louis-Hadrien Robert to
207 from 622. The talk is tomorrow, July 10, 1:30pm - 2:30pm. Room 207
has more board space and there was no air conditioning yesterday in 622,
hence the change.

Best,

Mikhail
