The saturation number of $\cb$-bounded stable monomial ideals and their powers
Reza Abdolmaleki, Jürgen Herzog, Guangjun Zhu
Let be the polynomial ring in variables over a field . In this paper, we compute the socle of $\cb$-bounded strongly stable ideals and determine that t…
Sortable Freiman ideals
Jürgen Herzog, Guangjun Zhu
In this paper it is shown that a sortable ideal is Freiman if and only if its sorted graph is chordal. This characterization is used to give a complete classification of Freima…
Regularity and projective dimension of powers of edge ideal of the disjoint union of some weighted oriented gap-free bipartite graphs
Guangjun Zhu, Li Xu, Hong Wang +1
In this paper we provide some precise formulas for regularity of powers of edge ideal of the disjoint union of some weighted oriented gap-free bipartite graphs. For the projective…
On the fiber cone of monomial ideals
Jürgen Herzog, Guangjun Zhu
We consider the fiber cone of monomial ideals. It is shown that for monomial ideals of height , generated by elements, the fiber cone of is a hy…
Projective dimension and regularity of edge ideals of some vertex-weighted oriented -partite graphs
Guangjun Zhu, Hong Wang, Li Xu +1
In this paper we provide some exact formulas for the projective dimension and the regularity of edge ideals associated to three special types of vertex-weighted oriented -partit…
Projective dimension and regularity of powers of edge ideals of vertex-weighted rooted forests
Li Xu, Guangjun Zhu, Hong Wang +1
In this paper we provide some exact formulas for projective dimension and the regularity of powers of edge ideals of vertex-weighted rooted forests. These formulas are functions of…
Regularity of powers of edge ideals of vertex-weighted oriented unicyclic graphs
Guangjun Zhu, Hong Wang, Li Xu +1
In this paper we provide some exact formulas for the regularity of powers of edge ideals of vertex-weighted oriented cycles and vertex-weighted unicyclic graphs. These formulas are…
