Numerical experiments with plectic Darmon points

Abstract: Let $E/F$ be an elliptic curve defined over a number field $F$, and let $K/F$ be a quadratic extension. If the analytic rank of $E(K)$ is one, one can often use Heegner points (or the more general Darmon points) to produce (at least conjecturally) a nontorsion generator of $E(K)$. If the analytic rank of $E(K)$ is larger than one, the problem of constructing algebraic points is still very open. In recent work, Michele Fornea and Lennart Gehrmann have introduced certain $p$-adic quantities that may be conjecturally related to the existence of these points. In this talk I will explain their construction, and illustrate with some numerical experiments some support for their conjecture. This is joint work with Michele Fornea and Xevi Guitart.
