摘要

本研究主要分析广义二叉边理想的深度。我们扩展了 d 兼容映射的概念,并利用它给出了广义二项式边理想深度的组合下限。随后,我们根据图的顶点连接性确定了广义二项式边理想的深度上限。我们证明,上界和下界之间的差异可以任意大,即使其中一个界限是尖锐的。此外,我们还计算了某些类别图的广义二项式边理想深度,包括循环图和具有科恩-麦考莱二项式边理想的图。

On the Depth of Generalized Binomial Edge Ideals

On the Depth of Generalized Binomial Edge Ideals

This research focuses on analyzing the depth of generalized binomial edge ideals. We extend the notion of d-compatible map and use it to give a combinatorial lower bound for the depth of generalized binomial edge ideals. Subsequently, we determine an upper bound for the depth of generalized binomial edge ideals in terms of the vertex-connectivity of graphs. We demonstrate that the difference between the upper and lower bounds can be arbitrarily large, even in cases when one of the bounds is sharp. In addition, we calculate the depth of generalized binomial edge ideals of certain classes of graphs, including cycles and graphs with Cohen-Macaulay binomial edge ideals.

期刊介绍: The Mediterranean Journal of Mathematics (MedJM) is a publication issued by the Department of Mathematics of the University of Bari. The new journal replaces the Conferenze del Seminario di Matematica dell’Università di Bari which has been in publication from 1954 until 2003. The Mediterranean Journal of Mathematics aims to publish original and high-quality peer-reviewed papers containing significant results across all fields of mathematics. The submitted papers should be of medium length (not to exceed 20 printed pages), well-written and appealing to a broad mathematical audience. In particular, the Mediterranean Journal of Mathematics intends to offer mathematicians from the Mediterranean countries a particular opportunity to circulate the results of their researches in a common journal. Through such a new cultural and scientific stimulus the journal aims to contribute to further integration amongst Mediterranean universities, though it is open to contribution from mathematicians across the world.
