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 cation: UQAM PK-5675\n DTSTART:20250108T190000Z DTEND:20250108T200000Z SUMMARY:Joseph Helfer (Simons Center for Geometry and Physics) URL:/mathstat/channels/event/joseph-helfer-simons-cent er-geometry-and-physics-362367 END:VEVENT END:VCALENDAR
