A Zariski theorem for monodromy of $A$-hypergeometric systems
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.

Summary: | 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. |
