%0 Journal Article %T Hyperplane arrangements of Torelli type %A Daniele Faenzi %A Daniel Matei %A Jean Vall¨¨s %J Mathematics %D 2010 %I arXiv %R 10.1112/S0010437X12000577 %X We give a necessary and sufficient condition in order for a hyperplane arrangement to be of Torelli type, namely that it is recovered as the set of unstable hyperplanes of its Dolgachev sheaf of logarithmic differentials. Decompositions and semistability of non-Torelli arrangements are investigated. %U http://arxiv.org/abs/1011.4611v1
