Published in 2020 at "Journal of Algebraic Combinatorics"

DOI: 10.1007/s10801-020-00939-2

Abstract: Let G be a simple graph on n vertices and $$J_G$$ denote the corresponding binomial edge ideal in $$S = K[x_1, \ldots , x_n, y_1, \ldots , y_n].$$ We prove that the Castelnuovo–Mumford regularity of… read more here.

Published in 2025 at "Journal of Algebraic Combinatorics"

DOI: 10.1007/s10801-025-01464-w

Abstract: In this article, we explore the class of graphs for which the projective dimension of the quotient of the binomial edge ideals matches the big height of that ideal. Additionally, we investigate the Vasconcelos number… read more here.

Published in 2020 at "Journal of Algebra"

DOI: 10.1016/j.jalgebra.2020.08.004

Abstract: Abstract In this article, we obtain an upper bound for the Castelnuovo-Mumford regularity of powers of an ideal generated by a homogeneous quadratic sequence in a polynomial ring in terms of the regularity of its… read more here.

Published in 2019 at "Journal of Algebra and Its Applications"

DOI: 10.1142/s0219498820501339

Abstract: We give a lower bound for the Castelnuovo-Mumford regularity of binomial edge ideals of block graphs by computing the two distinguished extremal Betti numbers of a new family of block graphs, called flower graphs. Moreover,… read more here.
