RaphaŽl Fino: Symmetric correspondences on quadrics


Submission: 2016, Nov 14

We prove a result comparing the rationality of some \textit{elementary} algebraic cycles introduced by Alexander Vishik, defined on orthogonal grassmannians, with the rationality of some algebraic cycles defined on fiber products of the corresponding quadric. %It is then applied to relate the rationality of these elementary cycles with the first Witt index of the quadric.
