Soergel Calculus with patches

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.
