A theory of stacks with twisted fields and resolution of moduli of genus two stable maps
Yi Hu, Jingchen Niu
We construct a smooth algebraic stack of tuples consisting of genus two nodal curves, simple effective divisors away from the nodes, and twisted fields. It provides a desingulariza…

Genus Two Stable Maps, Local Equations and Modular Resolutions
Yi Hu, Jun Li, Jingchen Niu
We provide a geometric construction of a sequence of modular blowups of the Artin stack parameterizing pre-stable pairs consisting of a genus-two nodal curve and a smooth divisor.…
