论文摘要
我们研究多符合理想的同源转移。在我们的主要定理中,我们证明,任何多功能理想的第一个同源性转移理想再次是多甲状腺,支持bandari,bayati和Herzog的猜想,该猜想预测了多甲状腺功能理想的所有同源性转移理想都是多甲状腺功能多的。这是一个很好的结果,我们恢复了Bayati的结果,该结果证明了这种猜想在无方案中。
We study the homological shifts of polymatroidal ideals. In our main theorem we prove that the first homological shift ideal of any polymatroidal ideal is again polymatroidal, supporting a conjecture of Bandari, Bayati and Herzog that predicts that all homological shift ideals of a polymatroidal ideal are polymatroidal. As a nice consequence, we recover a result of Bayati which proves this conjecture in the squarefree case.
