Affine extended weak order is a lattice

Grant T. Barkley, David E Speyer

Coxeter groups are equipped with a partial order known as the weak order, such that $u \leq v$ if the inversions of $u$ are a subset of the inversions of $v$ . In finite Coxeter gro…

Combinatorial invariance for Kazhdan-Lusztig $R$ -polynomials of elementary intervals

Grant T. Barkley, Christian Gaetz

We adapt the hypercube decompositions introduced by Blundell-Buesing-Davies-Veličković-Williamson to prove the Combinatorial Invariance Conjecture for Kazhdan-Lusztig $R$ -polynomia…
