Diagonal cycles and Euler systems. I: A $$p$$-adic Gross-Zagier formula. (Cycles de Gross-Schoen et systèmes d’Euler. I: Une formule de Gross-Zagier $$p$$-adique.) (English. French summary) Zbl 1356.11039
Summary: This article is the first in a series devoted to studying generalised Gross-Kudla-Schoen diagonal cycles in the product of three Kuga-Sato varieties and the Euler system properties of the associated Selmer classes, with special emphasis on their application to the Birch-Swinnerton-Dyer conjecture and the theory of Stark-Heegner points. The basis for the entire study is a $$p$$-adic formula of Gross-Zagier type which relates the images of these diagonal cycles under the $$p$$-adic Abel-Jacobi map to special values of certain $$p$$-adic $$L$$-functions attached to the Garrett-Rankin triple convolution of three Hida families of modular forms. The main goal of this article is to describe and prove this formula.
