On the Brauer-Manin obstruction for zero-cycles on curves

Number Theory 2007-05-23 v1 Algebraic Geometry

Abstract

We wish to give a short elementary proof of S. Saito's result that the Brauer-Manin obstruction for zero-cycles of degree 1 is the only one for curves, supposing the finiteness of the Tate-Shafarevich-group \sha1(A)\sha^1(A) of the Jacobian variety. In fact we show that we only need a conjecturally finite part of the Brauer-group for this obstruction to be the only one. We also comment on the situation in higher dimensions
