几类循环图的正则性

The regularity of some families of circulant graphs

Miguel Eduardo Uribe-Paczka, Adam Van Tuyl

摘要:

我们计算了两类循环图的边理想的Castelnuovo-Mumford正则性,其中包括所有的三次循环图。我们的方法的一个特点是结合上的正则性,的投射维数,和减少欧拉示性数,以获得一个准确的值的正则性。

英文摘要:

We compute the Castelnuovo-Mumford regularity of the edge ideals of two families of circulant graphs, which includes all cubic circulant graphs. A feature of our approach is to combine bounds on the regularity, the projective dimension, and the reduced Euler characteristic to derive an exact value for the regularity.
