The cones of g-vectors
Mohamad Haerizadeh, Siamak Yassemi
This paper studies the wall-chamber structures of finite-dimensional (-tilting infinite) algebras via generic decompositions of g-vectors. In particular, we examine regions out…

Induced matching, ordered matching and Castelnuovo-Mumford regularity of bipartite graphs
A. V. Jayanthan, S. A. Seyed Fakhari, I. Swanson +1
Let G be a finite simple graph and let indm(G) and ordm(G) denote the induced matching number and the ordered matching number of G, respectively. We characterize all bipartite grap…

The non-decreasing condition on g-vectors
Mohamad Haerizadeh, Siamak Yassemi
The non-decreasing condition on g-vectors is introduced. Our study shows that this condition is both necessary and sufficient to ensure that the generically indecomposable direct s…
