The Demazure operator associated to a simple reflection satisfies the twisted Leibniz rule. In this paper, we introduce a generalization of the twisted Leibniz rule for the Demazure operator associated to any atomic double coset. We prove that this atomic Leibniz rule is equivalent to a polynomial forcing property for singular Soergel bimodules.

Abstract
The Demazure operator associated to a simple reflection satisfies the twisted Leibniz rule. In this paper, we introduce a generalization of the twisted Leibniz rule for the Demazure operator associated to any atomic double coset. We prove that this atomic Leibniz rule is equivalent to a polynomial forcing property for singular Soergel bimodules.File in questo prodotto:
