Generalized mixed product ideals whose powers have a linear resolution
Monica La Barbiera, Roya Moghimipor
In this paper we study classes of monomial ideals for which all of its powers have a linear resolution. Let K[x_{1},x_{2}] be the polynomial ring in two variables over the field K,…
Combinatorial properties of strong quasi-n-partite graphs
Monica La Barbiera, Roya Moghimipor
Monomial ideals corresponding to strong quasi-n-partite graphs are considered. Some algebraic and combinatorial properties of generalized graph ideals of a strong quasi-n-partite g…
Combinatorics of the integral closure of edge ideals of strong quasi-n-partite graphs
Monica La Barbiera, Roya Moghimipor
Combinatorial properties of some ideals related to strong quasi-n-partites graphs are examined. We prove that the edge ideal of a strong quasi-n-partite graph is not integrally clo…
Polymatroidal property of generalized mixed product ideals
Monica La Barbiera, Roya Moghimipor
Let L be the generalized mixed product ideal induced by a monomial ideal I. In this paper, we study the polymatroidal property of generalized mixed product ideals. Furthermore, som…
Unmixedness of generalized Veronese bi-type ideals
Monica La Barbiera, Roya Moghimipor
In this paper, some algebraic invariants of generalized Veronese bi-type ideals are computed. We characterize the unmixed generalized Veronese bi-type ideals and we give a descript…
Generalized mixed product ideals
Jürgen Herzog, Roya Moghimipor, Siamak Yassemi
We consider classes of ideals which generalize the mixed product ideals introduced by Restuccia and Villarreal, and also generalize the expansion construction by Bayati and the fir…
