Paulin's geometric level raising conjecture for the eigencurve
Fix distinct primes and , and an integer coprime to . Let be the cuspidal eigencurve of tame level , parametrising overconvergent cuspidal -adic modular eigenforms. For a point of corresponding to an eigenform , let be the associated representation of . An irreducible connected component of is generically unramified principal series if the representations associated to its points away from a discrete set are unramified principal series, and generically special if they are special away from a discrete set. Let and be the roots of
where and are the and eigenvalues of . Paulin's geometric level raising conjecture. If is generically unramified principal series and there is a point on where the ratio of and is and is special, then there exists a generically special component intersecting at . This predicts that a special representation at a level-raising point lies on a component whose generic local representation is special, extending geometric level raising phenomena on the eigencurve beyond the cases established by the paper's theorem.
