Eric Panzer ( Oxford ) Integration with multiple polylogarithms
Abstract: Multiple polylogarithms are generalizations of the classical (poly-)logarithm functions and play an important role in several areas of mathematics. Their special values at one are well-known as multiple zeta values and these form the Drinfeld associator. Polylogarithms arise naturally as iterated integrals on the moduli space of genus zero curves, and their integration theory was worked out explicitly by F. Brown and is completely understood. I will define this class of functions, explain some of their properties, and show how they can be used to compute a certain class of integrals. Applications to Feynman integrals, string amplitudes and deformation quantization will be illustrated.

Sebastien Boucksom ( CMLS, Ecole Polytechnique ) Kähler-Einstein metrics
Abstract: Kähler metrics are a special class of Riemannian metrics, defined on complex manifolds, and locally expressed as the (complex) Hessian of a potential. Kähler metrics with constant Ricci curvature are called Kähler-Einstein, and come in three flavors, according to the curvature sign. I will review Aubin and Yau's classical existence and uniqueness results in the case of negative and zero curvature (Calabi-Yau metrics), and describe some aspects of the Yau- Tian-Donaldson conjecture, solved a few years ago, and which solves the existence problem in the case of positive curvature (Fano manifolds).
