Shellability and homology of $q$-complexes and $q$-matroids

Combinatorics 2021-05-20 v2 Algebraic Topology

Abstract

We consider a qq-analogue of abstract simplicial complexes, called qq-complexes, and discuss the notion of shellability for such complexes. It is shown that qq-complexes formed by independent subspaces of a qq-matroid are shellable. Further, we explicitly determine the homology of qq-complexes corresponding to uniform qq-matroids. We also outline some partial results concerning the determination of homology of arbitrary shellable qq-complexes..
