我们刻画了所有二项边理想具有线性分辨率的图。事实上,我们证明了完全图是唯一具有这个性质的图。我们还计算了图的二项式边理想的第一个Betti数相对于图项的一些梯度分量。最后给出了闭图二项边理想的Castelnuovo-Mumford正则性的上界。
We characterize all graphs whose binomial edge ideals have a linear resolution. Indeed, we show that complete graphs are the only graphs with this property. We also compute some graded components of the first Betti number of the binomial edge ideal of a graph with respect to the graphical terms. Finally, we give an upper bound for the Castelnuovo-Mumford regularity of the binomial edge ideal of a closed graph.
