Brauer groups and Tate-Shafarevich groups, by Cristian D. Gonzalez-Aviles

This is revised version of preprint 293. This new version differs from the old one in that it contains an Appendix in which we prove the compatibility of a certain "Cassels-Tate" pairing defined by Milne and an "Albanese-Picard" pairing defined by Poonen and Stoll. The proof uses biextensions and derived categories.
