AG : Exposé de Johannes Schmitt (ETH, Zürich) : Moduli spaces of twisted k-differentials and Pixton’s cycle
Bâtiment Fermat, salle 2105Johannes Schmitt (ETH - Zürich) Inside the moduli space of smooth genus g curves with n markings, there are the loci of curves admitting a meromorphic k-differential with prescribed zeros and poles at the marked points. We explain a compactification
