A stacky Castelnuovo's contraction theorem

 

Michele Pernice

KTH

 

In this talk, we are going to discuss a generalization to
weighted blowups of the classical Castelnuovo' contraction theorem.
Moreover, we will show as a corollary that the moduli stack of n-pointed
stable curves of genus 1 is a weighted blowup. This is a joint work with
Arena, Di Lorenzo, Inchiostro, Mathur, Obinna.
