+ | **On the asymptotics of Arakelov invariants** | ||
+ | |||
+ | We will discuss the asymptotics of invariants of Riemann | ||
+ | surfaces motivated by Arakelov theory. These invariants play a | ||
+ | fundamental role in bounds for the number of geometric torsion points on | ||
+ | curves. We will show that their asymptotic behaviour in families of | ||
+ | degenerating Riemann surfaces is controlled by their tropical counterparts. | ||

+ | The idea of the calculation of the Hilbert function of the moduli spaces of vector bundles on Riemann surfaces goes back to the works of Michael Thaddeus in the early 90’s. | ||
