DESCRIPTION:Title: The integral Chow ring of the moduli stack of compact ty
 pe curves of genus 2.\n\nAbstract: Computation of the Chow (and cohomology
 ) rings of moduli spaces of curves is a time honoured tradition in algebra
 ic geometry\, initiated by Mumford. In most cases where this has been done
 \, one computes only the *rational* Chow ring\, in which case the stack st
 ructure of the space plays no role. The computation of integral Chow rings
  is more delicate. In previous work\, E. Larson computed the integral Chow
  ring of \bar{M}_2. We extend this work and compute the integral Chow ring
  of the open substack of curves with compact Jacobian.\n\nThis is joint wo
 rk with Eric Jovinelly\, Eric Larson\, Anda Tenie\, and Chenxi Wang.\n\nLo
