I will talk about a recent result that shows that any sufficiently nice even analytic function can be recovered from its values at the nontrivial zeros of \zeta(1/2+is) and the values of its Fourier transform at logarithms of integers. The proof is based on an explicit interpolation formula, whose construction relies on a strengthening of Knopp's abundance principle for Dirichlet series with functional equations. The talk is based on a joint work with Andriy Bondarenko and Kristian Seip.

Hitchin components are generalizations of the classical Teichmüller space. I will describe a program to describe Hitchin components as the moduli space of some new geometric structure on the surface. This geometric structure generalizes the complex structure. Its construction uses the punctual Hilbert scheme of the plane. It should give a unified description of Hitchin components without fixed complex structure on the surface.

A paracomplex Deligne—Mumford stack is considered. This structure introduces additional conical singularities, in the neighbourhood of which the curvature is negative.

Modular forms appear in Poincaré's work as solutions of second order linear ODEs defined on hyperbolic Riemann surfaces. These differential equations, called uniformizing ODEs, were classically related to the study of the universal cover of (hyperbolic) Riemann surfaces.
