Title: Spectral Halo of Eigencurves Speaker: Bin Zhao (MCM) Time: 2019-11-14, 10:30-11:30 Place: MCM110 Abstract: In a previous work of Ruochuan Liu, Daqing Wan and Liang Xiao, they proved that over the boundary of the weight disc, most components of the eigencurve are disjoint unions of spaces finite flat over the weight disc. In this talk, I will explain a joint work with Liang Xiao on a refinement of this result. A main ingredient in the proof is a down to earth computation of the projective envelope of a Serre weight.
