Following a suggestion of Peter Scholze, we construct an action ofon the Katz moduli problem, a profinite-étale cover of the ordinary locus of the-adic modular curve whose ring of functions is Serre’s space of-adic modular functions. This action is a local,-adic analog of a global, archimedean action of the circle groupon the lattice-unstable locus of the modular curve over. To construct the-action, we descend a moduli-theoretic action of a larger group on the (big) ordinary Igusa variety of Caraiani-Scholze. We compute the action explicitly on local expansions and find it is given by a simple multiplication of the cuspidal and Serre-Tate coordinates; along the way we also prove a natural generalization of Dwork’s equationfor extensions ofbyvalid over a non-Artinian base. Finally, we give a direct argument (without appealing to local expansions) to show that the action ofintegrates the differential operatorcoming from the Gauss-Manin connection and unit root splitting, and explain an application to Eisenstein measures and-adic-functions.
