Bound for the Regularity of Binomial Edge Ideals of Cactus Graphs
《Algebra Colloquium》2022年第3期443-452,共10页A.V.Jayanthan Rajib Sarkar 
funded by University Grants Commission,India.
In this article,we obtain an upper bound for the regularity of the binomial edge ideal of a graph whose every block is either a cycle or a clique.As a consequence,we obtain an upper bound for the regularity of binomia...

Cost Edge-Coloring of a Cactus
《World Journal of Engineering and Technology》2015年第3期119-134,共16页Zhiqian Ye Yiming Li Huiqiang Lu Xiao Zhou 
Let C be a set of colors, and let ?be an integer cost assigned to a color c in C. An edge-coloring of a graph ?is assigning a color in C to each edge ?so that any two edges having end-vertex in common have different c...
