Abstract: Fix a prime p. We generalize our early method of computing overconvergent lifts of ordinary p-adic homology classes for SL_3 to allow computations of lifts of non-ordinary, but numerically non-critical classes. Then we will discuss an ongoing calculation to find to any desired degree of accuracy the germ of the projection to weight space of the eigencurve Z around the point z corresponding to the system of Hecke eigenvalues of this over convergent lift. We do this under the conjecturally mild hypothesis that Z is smooth at z. This is joint work with Avner Ash.
