Title:  Modular Resolution of the Moduli Space of Genus 2 Stable Maps

Abstract:   We describe a (huge) sequence of modular blowups of the relative Picard stack of the Artin stack of pre-stable weighted genus 2 curves. The sequence of blowups diagonalizes certain tautological derived objects. This provides a resolution of the primary component of the moduli space of genus 2 stable maps to projective space and a partial desingularization of the same moduli space. Joint work with Yi Hu and Jun Li.
