Fundamental groups of symmetric sextics II

Abstract

We study the moduli spaces and compute the fundamental groups of plane sextics of torus type with the set of inner singularities 2A8 or A17. We also compute the fundamental groups of a number of other sextics, both of and not of torus type. The groups found are simplest possible, that is, ℤ2ℤ3 and ℤ6 respectively. © 2009 London Mathematical Society.
