Title:
A Thom Sebastiani principle for braid monodromy and divisor knot groups
Abstract:
The talk will address the problem of divisor knot groups, i.e. fundamental groups
of divisor complements, in a particular setting. The divisor is given as the graph
of a function which is the sum of functions in independent sets of variables.
We will relate the braid monodromies of the summands with the braid monodromy
of the sum, thereby obtaining a presentation of the divisor knot group.
Time permitting, we will give applications to discriminant knot groups.
