Título: From Deligne-Mostow Theory to Dunkl Connections II

Resumo: In the 80's of last century, Deligne and Mostow studied the monodromy problem of Lauricella hypergeometric functions and gave a rigorous treatment on the subject, which provides ball quotient structures on $\mathbb{P}^n$ minus a hyperplane configuration of type $A_{n+1}$. Then some 20 years later Couwenberg, Heckman and Looijenga developed it to a more general setting by means of the Dunkl connection, which deals with the geometric structures on projective arrangement complements. In this talk, I will briefly review the Deligne-Mostow theory first and then explain how to look at it from the point of view of geometric structures on arrangement complements.
