On the algebraic Sato鈥揟ate conjecture for abelian varieties
On the algebraic Sato鈥揟ate conjecture for abelian varieties
The Sato鈥揟ate conjecture, originally stated for elliptic curves on 1963, predicts the equidistribution of the normalized Frobenius traces with respect to the Sato鈥揟ate measure, given by the pushforward of the Haar measure on SU(2). We would like to work on an analogous question for abelian varieties of dimension g > 1; the generalized Sato鈥揟ate conjecture, introduced by Serre, which predicts the equidistribution on a certain compact Lie group: the Sato鈥揟ate group. In 1966, Serre presented remarkable links between the Mumford鈥揟ate group and the Sato鈥揟ate group. Thus, the algebraic Sato鈥揟ate group appears as an intermediate group between the Mumford鈥揟ate group and the Sato鈥揟ate group. Indeed, if the algebraic Sato鈥揟ate conjecture holds (which is a refinement of the Mumford鈥揟ate conjecture) for some particular abelian variety A of dimension g > 1, we can obtain the Sato鈥揟ate group and try to deduce some new instances of the generalized Sato鈥揟ate conjecture. The main goal of this talk is to present new results in the direction of the algebraic Sato鈥揟ate conjecture, building on the previous work of Serre, Kedlaya and Banaszak.
