Abstract
We define and study the -partial alternating sign matrix polytope, motivated by connections to the Chan-Robbins-Yuen polytope and the -Tamari lattice. We determine the inequality description and show this polytope is a face of the partial alternating sign matrix polytope of [Heuer, Striker 2022]. We show that the -partial ASM polytope is an order polytope and a flow polytope.
