[PDF][PDF] Orbifold thechniques in degeneration formulas
D Abramovich, B Fantechi - ANNALI SCUOLA NORMALE …, 2016 - journals.sns.it
We give a new approach for relative and degenerate Gromov-Witten invariants, inspired by
that of Jun Li but replacing predeformable maps by transversal maps to a twisted target. The …

Higher rank stable pairs and virtual localization
A Sheshmani - arXiv preprint arXiv:1011.6342, 2010 - arxiv.org
We introduce a higher rank analog of the Pandharipande-Thomas theory of stable pairs on a
Calabi-Yau threefold $ X $. More precisely, we develop a moduli theory for frozen triples …

Virtual classes of -gerbes
F Qu - manuscripta mathematica, 2021 - Springer
We show that a perfect obstruction theory for a G _ m G m-gerbe determines a semi-perfect
obstruction theory for its base, which is perfect if the gerbe is quasi-compact and affine …

Gromov-Witten theory of tame Deligne-Mumford stacks in mixed characteristic
F Poma - arXiv preprint arXiv:1210.2269, 2012 - arxiv.org
We define Gromov-Witten classes and invariants of smooth proper tame Deligne-Mumford
stacks of finite presentation over a Dedekind domain. We prove that they are deformation …
