Direct Images Of Locally Constant Sheaves on Complements to Plane Line Arrangements
2015 (English)Licentiate thesis, monograph (Other academic)
On the complement (where each is a line passing through the origin) to a plane line arrangement , a locally constant sheaf of complex vector spaces is given by a multi-index . Using the description of Mac-Pherson and Vilonen ( and ) we obtain a criterion for the irreducibility of the direct image as a perverse sheaf, where is the canonical inclusion.
