我们研究具有有限数量的定义关系和庞加莱级数 Σdnxn 生成器的分级代数齐次分量的维数 dn 的增长。证明了如果定义关系是词,则庞加莱级数是有理函数。在一般情况下,证明了不等式将维度 dn 的数量与定义关系及其程度的生成元的数量联系起来。
We study the growth in the number of dimensions dn of the homogeneous component of a graded algebra with a finite number of defining relations and generators for the Poincaré series Σdnxn. It is proved that if the defining relations are words, the Poincaré series is a rational function. In the general case inequalities are proved linking the number of dimensions dn with the number of generators defining relations and their degree.
