This paper gives exact formulas for the regularity of powers of edge ideals of an edge-weighted integrally closed cycle.
Powers of edge ideals of edge-weighted trees
Jiaxin Li, Guangjun Zhu, Shiya Duan
This paper gives exact formulas for the regularity of edge ideals of edge-weighted integrally closed trees. In addition, we provide some linear upper bounds on the regularity of po…
Edge ideals of some edge-weighted graphs
Guangjun Zhu, Shiya Duan, Yijun Cui +1
This paper presents exact formulas for the regularity and depth of powers of edge ideals of an edge-weighted star graph. Additionally, we provide exact formulas for the regularity…
Integral closure and normality of edge ideals of some edge-weighted graphs
Shiya Duan, Guangjun Zhu, Yijun Cui +1
Let be an edge-weighted simple graph. In this paper, we give a complete characterization of the graph whose edge ideal is integrally closed. We also show that…
