Title : Periods of unit root and Overconvergent Igusa Towers, Part II. Abstract: .November 17 : V. Pilloni (Columbia U.). Title : Overconvergent Modular Forms and Abelian Surfaces. Abstract: Yoshida's Conjecture predicts the existence of a Siegel modular form attached to any abelian surface defined over the rationals. In certain cases, one can prove this correspondence by replacing modular forms by overconvergent modular forms. We shall explain a plausible strategy to prove that these overconvergent Siegel modular forms are actually classical, hence that these abelian surfaces actually come from classical Siegel modular forms.
