我们将分支覆盖的单值群与其限制的单值群联系起来。我们证明,在限制单值群中存在一个对换会显著约束原始分支覆盖的单值群。利用这一结果,我们完善了稀疏迹检验算法,该算法用于数值验证稀疏多项式系统的一组解是否完备。在此过程中,我们在分支覆盖的框架下发展了迹检验概念的推广。
英文摘要
We relate the monodromy group of a branched cover to the monodromy groups of its restrictions. We show that the presence of a transposition in a restricted monodromy group significantly constrains the monodromy group of the original branched cover. Using this result, we complete the sparse trace test algorithm, which numerically verifies whether a set of solutions to a sparse polynomial system is complete. Along the way, we develop a generalization of the notion of a trace test in the setting of branched covers.
