具有拟常重数的Coxeter多重排列
Coxeter multiarrangements with quasi-constant multiplicities
摘要:
利用本原导子研究了具有拟常重数的Coxeter多重排列的导子模的结构。作为应用,我们证明了具有拟常重数的Coxeter多重排列的特征多项式是组合可计算的。
英文摘要:
We study structures of derivation modules of Coxeter multiarrangements with quasi-constant multiplicities by using the primitive derivation. As an application, we show that the characteristic polynomial of a Coxeter multiarrangement with quasi-constant multiplicity is combinatorially computable.
