论文摘要
我们提供的条件下，在$ a $ a $ a $集合的修改下，$ a $ hyphemetric systry的单片组是不变的。关键成分是Zariski - lefschetz type定理，用于$ a $ a $ a-diderminats。
We give conditions under which the monodromy group of an $A$-hypergeometric system is invariant under modifications of the collection of characters $A$. The key ingredient is a Zariski--Lefschetz type theorem for principal $A$-determinants.
