本文提供了深入了解对称性的作用,在研究多项式函数消失到高阶代数簇。我们研究的品种是奇异轨迹的超平面安排在射影空间,重点安排所产生的复杂的反射群。我们提供了最小的方程组定义这些奇异轨迹的激进理想和研究这些理想的普通和象征性的权力之间的包容性。我们的工作将Bauer等人(Int Math Res Not IMRN 24:7459-7514,2019),Dumnicki等人(J Algebra 393:24-29,2013),Harbourne和Seceleanu(J Pure Appl Algebra 219(4):1062-1072,2015)以及Malara和Szpond(J Pure Appl Algebra 222(8):2323-2329,2018)中的结果联系在一起并在统一的方法下推广。
This paper provides insights into the role of symmetry in studying polynomial functions vanishing to high order on an algebraic variety. The varieties we study are singular loci of hyperplane arrangements in projective space, with emphasis on arrangements arising from complex reflection groups. We provide minimal sets of equations for the radical ideals defining these singular loci and study containments between the ordinary and symbolic powers of these ideals. Our work ties together and generalizes results in Bauer et al. (Int Math Res Not IMRN 24:7459–7514, 2019), Dumnicki et al. (J Algebra 393:24–29, 2013), Harbourne and Seceleanu (J Pure Appl Algebra 219(4):1062–1072, 2015) and Malara and Szpond (J Pure Appl Algebra 222(8):2323–2329, 2018) under a unified approach.
