ODTÜ-BİLKENT ALGEBRAIC GEOMETRY SEMINAR

“Trigonal Curves and Monodromy II”

By

Alexander Degtyarev

(BİLKENT UNIVERSITY)

Abstract: We will discuss the fundamental groups, braid monodromy, Zariski--van Kampen theorem, and the relation between the braid monodromy, dessins, and the j-invariant, implying that the monodromy group is one of genus zero and imposing strong restrictions on the fundamental group. Another application of this ideology is the concept of universal (for a given fundamental group) trigonal curve.
