Castelnuovo-Mumford regularity of generalized binomial edge ideals of graphs

Dariush Kiani, Sara Saeedi Madani, Guangjun Zhu

In this paper, we mainly study the Castelnuovo-Mumford regularity of the generalized binomial edge ideals of graphs. We show that this number can be any integer number from to…

Combinatorial upper bounds for the smallest eigenvalue of a graph

Aryan Esmailpour, Sara Saeedi Madani, Dariush Kiani

Let be a graph, and let denote the smallest eigenvalue of . First, we provide an upper bound for based on induced bipartite subgraphs of . Consequently, we…

Cycle algebras and polytopes of matroids

Tim Römer, Sara Saeedi Madani

Cycle polytopes of matroids have been introduced in combinatorial optimization as a generalization of important classes of polyhedral objects like cut polytopes and Eulerian subgra…

Induced matchings in strongly biconvex graphs and some algebraic applications

Sara Saeedi Madani, Dariush Kiani

In this paper, motivated by a question posed in \cite{AH}, we introduce strongly biconvex graphs as a subclass of weakly chordal and bipartite graphs. We give a linear time algorit…

Regularity of binomial edge ideals of chordal graphs

M. Rouzbahani Malayeri, S. Saeedi Madani, D. Kiani

In this paper we prove the conjectured upper bound for Castelnuovo-Mumford regularity of binomial edge ideals posed in [23], in the case of chordal graphs. Indeed, we show that the…

Some Cohen-Macaulay and unmixed binomial edge ideals

Dariush Kiani, Sara Saeedi Madani

We study unmixed and Cohen-Macaulay properties of the binomial edge ideal of some classes of graphs. We compute the depth of the binomial edge ideal of a generalized block graph. W…

Algebraic properties of ideals of poset homomorphisms

Martina Juhnke-Kubitzke, Lukas Katthän, Sara Saeedi Madani

Given finite posets and , we consider a specific ideal , whose minimal monomial generators correspond to order-preserving maps . We study algebraic…

The edge ideals of complete multipartite hypergraphs

Dariush Kiani, Sara Saeedi Madani

We classify all complete uniform multipartite hypergraphs with respect to some algebraic properties, such as being (almost) complete intersection, Gorenstein, level, -Cohen-Maca…
