The document discusses a conjectural p-adic construction of elliptic curves attached to modular forms over number fields. It proposes using p-adic path integrals to define periods of the elliptic curves in terms of cohomology classes of certain arithmetic groups. Specifically, the period lattice would be generated by integrals of a modular form's cohomology class against cycles representing the boundary of the Bruhat-Tits tree. This aims to make the modularity conjecture constructive in a non-archimedean setting.
