论文摘要
我们介绍了伯格曼的粉丝,并证明了伯格曼风扇的盘子环与多膜状体的杂烩环是同构的。使用Bergman风扇,我们为多甲状腺的Chow环建立了Kähler包装,从而恢复并加强了Pagaria-Pezzoli的结果。
We introduce the Bergman fan of a polymatroid and prove that the Chow ring of the Bergman fan is isomorphic to the Chow ring of the polymatroid. Using the Bergman fan, we establish the Kähler package for the Chow ring of the polymatroid, recovering and strengthening a result of Pagaria-Pezzoli.
