Some computations on the characteristic variety of a line arrangement

Abstract

We find monodromy formulas for line arrangements which are fibered with respect to the projection from one point. We use them to find $0$-dimensional translated components in the first characteristic variety of the arrangement $\mathcal{R}(2n)$ determined by a regular $n$-polygon and its diagonals.
