Abstract
We find monodromy formulas for line arrangements that 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 [InlineEquation not available: see fulltext.] determined by a regular n-polygon and its diagonals. We also find new 1-dimensional translated components which generalize the well-known case of the B3-deleted arrangement. © 2020, The Author(s).File in questo prodotto:
