Title: Hurwitz Monodromy

Abstract: families of branched covers of the Riemann sphere 
with fixed ramification type may be described via Hurwitz 
spaces. In this talk, we will consider the case where the 
Hurwitz space is a Riemann surface and may be viewed as a 
branched cover of the Riemann sphere. We will review how 
one can calculate the monodromy of this cover (Huritz 
monodromy) in terms of Nielsen tuples by explicit formulas. 
Moreover, in certain cases, it is possible to calculate 
the Hurwitz monodromy of quotients of covers via the 
Nielsen tuples of the original ones.
