幂零$k[T]$ -模的泛型扩张扩张、划分幺半群和Hall多项式的常数项

Generic extensions of nilpotent $k[T]$-modules, monoids of partitions and constant terms of Hall polynomials

Justyna Kosakowska

摘要:

证明了有限维幂零$k[T]$ -模的泛型扩张幺半群同构于分划幺半群(有附加分划).此外,我们还给出了计算经典霍尔多项式的常数项的组合算法。

英文摘要:

We prove that the monoid of generic extensions of finite dimensional nilpotent $k[T]$-modules is isomorphic to the monoid of partitions (with addition of partitions). Moreover we give a combinatorial algorithm that calculates constant terms of classical Hall polynomials.
