Special values of L-function of elliptic curves over $\mathbf{Q}$ and their base change to real quadratic fields
Abstract. Motivated by a result of Bertolini?Darmon on Stark?Heegner points, we study the special value of the L-function of a rational elliptic curve, base-changed to a real quadratic field. The conjecture of Birch and Swinnerton-Dyer predicts that such value, appropriately normalized, is a perfect square. If time permits, we will reformulate this prediction in terms of a conjecture about Petersson inner products of automorphic forms on definite quaternion algebras.
