The existence of Hall polynomials for posets of finite prinjective type
摘要:
证明了有限主射型的有限偏序集的主射表示的Hall多项式的存在性。在第4节中,我们简要讨论了霍尔多项式存在的后果,特别是,我们能够定义一个一般的Ringel-Hall代数的有限主射型偏序集的主射表示。
英文摘要:
We prove the existence of Hall polynomials for prinjective representations of finite partially ordered sets of finite prinjective type. In Section 4 we shortly discuss consequences of the existence of Hall polynomials, in particular, we are able to define a generic Ringel-Hall algebra for prinjective representations of posets of finite prinjective type.
