AI总结:

本文研究Jayanthan等人2021年提出的关于树或单圈图的二项边理想是否为线性型的猜想,验证了该猜想对树成立,发现并非所有单圈图都符合该猜想。

摘要:

交换环R中的理想I若其Rees代数与对称代数同构,则称I为线性型。本文研究Jayanthan、Kumar和Sarkar(2021)提出的猜想:若G是树或单圈图,则G的二项边理想为线性型。我们的研究验证了该猜想对树成立,但发现并非所有单圈图都符合该猜想。

英文摘要:

An ideal $I$ of a commutative ring $R$ is said to be of linear type when its Rees algebra and symmetric algebra exhibit isomorphism. In this paper, we investigate the conjecture put forth by Jayanthan, Kumar, and Sarkar (2021) that if $G$ is a tree or a unicyclic graph, then the binomial edge ideal of $G$ is of linear type. Our investigation validates this conjecture for trees. However, our study reveals that not all unicyclic graphs adhere to this conjecture.
