Juergen Herzog, Takayuki Hibi, Hidefumi Ohsugi

摘要:

给出了分次理想的幂是分量线性的判别准则。我们的标准可以应用的典型例子包括某些有限图的顶点覆盖理想。

英文摘要:

We give criteria for graded ideals to have the property that all their powers are componentwise linear. Typical examples to which our criteria can be applied include the vertex cover ideals of certain finite graphs.
