Algebra Seminar: Maltoni -- Soergel Calculus with patches

Leonardo Maltoni (ANU) will be speaking in the algebra seminar.  We will go out for
lunch after the talk---all are welcome to join! 

When: 12-1pm Friday May 30 

Where: Carslaw 175 

Title: Soergel Calculus with patches 

Abstract: Elias and Williamson gave a presentation by generators and relations of the
Hecke category in terms of Soergel diagrams.  One can adapt this presentation to
describe a dg version of the category of Rouquier complexes.  I will describe the basic
properties of this category and some results about Rouquier complexes that can be
obtained from this point of view via Discrete Morse Theory techniques.
