关联代数的分次及其分次多项式恒等式

Gradings on Incidence Algebras and their Graded Polynomial Identities

Humberto Luiz Talpo, Waldeck Schützer

摘要:

设P是局部有限的偏序集,F是域,G是群,I(P,F)是P在F上的关联代数.我们描述了这个代数上的所有不等价的初等G-分次。若P是有界的,F是特征为零的无限域,A,B都是满足相同G-分次多项式恒等式的初等G-分次关联代数,且P的自同构群传递作用在P的极大链上,则证明了A,B是分次同构的.

英文摘要:

Let P a locally finite partially ordered set, F a field, G a group, and I(P,F) the incidence algebra of P over F. We describe all the inequivalent elementary G-gradings on this algebra. If P is bounded, F is a infinite field of characteristic zero, and A, B are both elementary G-graded incidence algebras satisfying the same G-graded polynomial identities, and the automorphisms group of P acts transitively on the maximal chains of P , we show that A and B are graded isomorphic.
