On the monodromy action on Milnor fibers of graphic arrangements
arXiv:math/0609075 · doi:10.1016/j.topol.2008.09.014
Abstract
We analyze the monodromy action, over the rationals, on the first homology group of the Milnor fiber, for arbitrary subarrangements of Coxeter arrangements. We propose a combinatorial formula for the monodromy action, involving Aomoto complexes in positive characteristic. We verify the formula, in cases A, B and D.
