In this paper we introduce the stack of polarized twisted conics and we use it to give a new point of view on the stack of stable curves of genus 2. In particular, we present a new and independent approach to the computation of its integral Chow ring, previously determined by Eric Larson.

Abstract
In this paper we introduce the stack of polarized twisted conics and we use it to give a new point of view on the stack of stable curves of genus 2. In particular, we present a new and independent approach to the computation of its integral Chow ring, previously determined by Eric Larson.File in questo prodotto:
