Isotropic meta Kazhdan--Lusztig combinatorics I: Ext-quiver presentation for the Hecke category
Abstract
We provide an Ext-quiver and relations presentation for the basic algebra of the anti-spherical Hecke categories of isotropic Grassmannians, H(Dn, An-1), in terms of cup-cap meta Kazhdan--Lusztig combinatorics and Temperley--Lieb diagrammatics.
