Abstract: Soregel bimodules are the primary tools in the recently announced proof by Elias-Williamson of the positivity of the coefficients of Kazhdan-Lusztig polynomials for Coxeter groups. I will define these and explore some examples. Time permitting, I will explain how these are used in Schubert calculus.
