仙人掌图的二项式边理想正则性的界

Bound for the regularity of binomial edge ideals of cactus graphs

A. V. Jayanthan, Rajib Sarkar

摘要:

在这篇文章中,我们获得了每个块都是圈或团的图的二项边理想的正则性的上界。作为结果,我们得到了仙人掌图的二项式边理想的正则性的一个上界。我们还确定某些子类达到上界。

英文摘要:

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 binomial edge ideal of a cactus graph. We also identify certain subclass attaining the upper bound.
