%0 Journal Article %T D-affinity and Frobenius morphism on quadrics %A Adrian Langer %J Mathematics %D 2007 %I arXiv %X We compute decomposition of Frobenius push-forwards of line bundles on quadrics into a direct sum of line bundles and spinor bundles. As an application we show when the Frobenius push-forward gives a tilting bundle and we apply it to study D-modules on quadrics. %U http://arxiv.org/abs/0707.0915v2
