Linear resolutions and Gröbner basis of Hankel determinantal ideals

Sepehr Jafari

In this paper, we study the family of determinantal ideals of "close" cuts of Hankel matrices, say $f$ . We show that the multi-Rees algebra of ideals in $f$ …

Regularity of bicyclic Graphs and their powers

Yairon Cid-Ruiz, Sepehr Jafari, Navid Nemati +1

Let $I (G)$ be the edge ideal of a bicyclic graph. In this paper, we characterize the Castelnuovo-Mumford regularity of $I (G)$ in terms of the induced matching number of $G$ . For th…
