Mads Christensen (UCL):Linking numbers and non-holomorphic Siegel modular forms

In an arithmetic hyperbolic 3-manifold there is an abundance of naturally defined closed geodesics. I will present a result which relates linking number invariants of these geodesics to the Fourier coefficients of certain non-holomorphic Siegel modular forms of genus 2. .
