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…
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…
