Decomposition of Perverse Sheaves on Plane Line Arrangements

Rikard Bøgvad, Iara Gonçalves

On the complement $X = C^{2} - ⋃_{i = 1}^{n} L_{i}$ to a central plane line arrangement $⋃_{i = 1}^{n} L_{i} \subset C^{2}$ , a locally constant sheaf of complex vect…

Length and decomposition of the cohomology of the complement to a hyperplane arrangement

Rikard Bøgvad, Iara Gonçalves

Let $A$ be a hyperplane arrangement in $C^{n}$ . We show that the number of decomposition factors as a perverse sheaf of the direct image $R j_{*} C_{U}$ of the co…
