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…
Moduli of Curves of Genus One with Twisted Fields
Yi Hu, Jingchen Niu
We construct a smooth Artin stack parameterizing the stable weighted curves of genus one with twisted fields and prove that it is isomorphic to the blowup stack of the moduli of ge…
Lower Bounds for Enumerative Counts of Positive-Genus Real Curves
Jingchen Niu, Aleksey Zinger
We transform the positive-genus real Gromov-Witten invariants of many real-orientable symplectic threefolds into signed counts of curves. These integer invariants provide lower bou…
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.…
