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 outs…
Lyubeznik tables of and rings
Josep Àlvarez Montaner, Siamak Yassemi
We describe the shape of the Lyubeznik table of either rings in positive characteristic or Stanley-Reisner rings in any characteristic when they satisfy Serre's condition or…
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…
Differences in regularities of a power and its integral closure and symbolic power
Irena Swanson, Siamak Yassemi
We show that for a square-free monomial ideal, the regularity of its symbolic (second) power and of the integral closure of of its (second) power can differ from the regularity of…
Cohen-Macaulay edge-weighted edge ideals of very well-covered graphs
Seyed Amin Seyed Fakhari, Kosuke Shibata, Naoki Terai +1
We characterize unmixed and Cohen-Macaulay edge-weighted edge ideals of very well-covered graphs. We also provide examples of oriented graphs which have unmixed and non-Cohen-Macau…
