Abstract
Eigenvarieties and twisted eigenvarieties Zhengyu Xiang For an arbitrary reductive group G, we construct the full eigenvariety E, which parameterizes all p-adic overconvergent cohomological eigenforms of G in the sense of Ash-Stevens and Urban. Further, given an algebraic automorphism ι of G, we construct the twisted eigenvariety E, a rigid subspace of E, which parameterizes all eigenforms that are invariant under ι. In particular, in the case G = GLn, we prove that every self-dual automorphic representation can be deformed into a family of self-dual cuspidal forms containing a Zariski dense subset of classical points. This is the inverse of Ash-Pollack-Stevens conjecture. We also give some hint to this conjecture.
