Orlik--Solomon sheaf homology of geometric lattices

Ye Liu

We associate the Orlik--Solomon sheaf with a finite geometric lattice and compute its sheaf homology. We show that this homology concentrates in top degree, admitting a convolution…

$G$ -Tutte polynomials and abelian Lie group arrangements

Ye Liu, Tan Nhat Tran, Masahiko Yoshinaga

We introduce and study the notion of the $G$ -Tutte polynomial for a list $A$ of elements in a finitely generated abelian group $Γ$ and an abelian group $G$ , which is defi…

On chromatic functors and stable partitions of graphs

Ye Liu

The chromatic functor of a simple graph is a functorization of the chromatic polynomial. M. Yoshinaga showed in \cite{Yoshinaga2015} that two finite graphs have isomorphic chromati…
