p-adic Heights of Heegner points on Shimura curves

TL;DR

This paper constructs a $p$-adic $L$-function for Hilbert modular forms and relates its derivative to the $p$-adic height of Heegner points, extending Gross--Zagier formulas to totally real fields.

Contribution

It provides an explicit construction of a $p$-adic Rankin-Selberg $L$-function and proves a $p$-adic Gross--Zagier formula for Hilbert modular forms over totally real fields.

Findings

The central derivative of the $p$-adic $L$-function equals the $p$-adic height of a Heegner point.

Generalization of Gross--Zagier formula to totally real fields.

Applications to $p$-adic and classical Birch and Swinnerton-Dyer conjectures.

Abstract

Let $f$ be a primitive Hilbert modular form of parallel weight $2$ and level $N$ for the totally real field $F$, and let $p$ be a rational prime coprime to $2N$. If $f$ is ordinary at $p$ and $E$ is a CM extension of $F$ of relative discriminant $\Delta$ prime to $Np$, we give an explicit construction of the $p$-adic Rankin-Selberg $L$-function $L_{p}(f_E,\cdot)$. When the sign of its functional equation is $-1$, we show, under the assumption that all primes $\wp\vert p$ are principal ideals of ${\mathcal O}_{F}$ which split in ${\mathcal O}_{E}$, that its central derivative is given by the $p$-adic height of a Heegner point on the abelian variety $A$ associated with $f$. This $p$-adic Gross--Zagier formula generalises the result obtained by Perrin-Riou when $F={\mathbf Q}$ and $(N,E)$ satisfies the so-called Heegner condition. We deduce applications to both the $p$-adic and the classical Birch and Swinnerton-Dyer conjectures for~$A$.
