A Hom formula for Soergel modules
Leonardo Patimo
We study Soergel modules for arbitrary Coxeter groups. For infinite Coxeter groups, we show that the homomorphisms between Soergel modules are in general more than those coming fro…

On the Induction of p-Cells
Lars Thorge Jensen, Leonardo Patimo
We study cells with respect to the -canonical basis of the Hecke algebra of a crystallographic Coxeter system (see arXiv:1510.01556, arXiv:1901.02323) and their compatibility wi…

The Néron-Severi Lie Algebra of a Soergel Module
Leonardo Patimo
We introduce the Néron-Severi Lie algebra of a Soergel module and we determine it for a large class of Schubert varieties. This is achieved by investigating which Soergel modules a…
