Double integrals and transformation formulas for Appell--Lauricella hypergeometric functions
Shihao Wang, Chenglong Yu, Zhiwei Zheng
The monodromy of hypergeometric functions can govern the properties of the functions themselves. Previously, the second and third authors studied the commensurability relations amo…

Moduli spaces of sextic curves with simple singularities and their compactifications
Chenglong Yu, Zhiwei Zheng, Yiming Zhong
In this paper, we study moduli spaces of sextic curves with simple singularities. Through period maps of K3 surfaces with ADE singularities, we prove that such moduli spaces admit…

Commensurability Among Deligne-Mostow Monodromy Groups
Chenglong Yu, Zhiwei Zheng
This paper gives the commensurability classification of Deligne--Mostow ball quotients and shows that the 104 Deligne--Mostow lattices form 38 commensurability classes. First, we f…
