%0 Journal Article %T Cohomology jump loci of quasi-projective varieties %A Nero Budur %A Botong Wang %J Mathematics %D 2012 %I arXiv %X We prove that the cohomology jump loci in the space of rank one local systems over a smooth quasi-projective variety are finite unions of torsion translates of subtori. The main ingredients are a recent result of Dimca-Papadima, some techniques introduced by Simpson, together with properties of the moduli space of logarithmic connections constructed by Nitsure and Simpson. %U http://arxiv.org/abs/1211.3766v2
