Let be a modular eigenform of even weight and new at a prime dividing exactly the level with respect to an indefinite quaternion algebra. The theory of Fontaine-Mazur allows to attach to a monodromy module and an -invariant . The first goal of this paper is building a suitable -adic integration theory that allows us to construct a new monodromy module and -invariant , in the spirit of Darmon. The two monodromy modules are isomorphic, and in particular the two -invariants are equal.
Let be a real quadratic field and assume the sign of the functional equation of the -series of over is . The Bloch-Beilinson conjectures suggest that there should be a supply of elements in the Selmer group of the motive attached to over the tower of narrow ring class fields of . Generalizing work of Darmon for , we give a construction of local cohomology classes which we expect to arise from global classes and satisfy an explicit reciprocity law, accounting for the above prediction.
