Cosection Localization and Vanishing for Virtual Fundamental Classes of D-Manifolds

Algebraic Geometry 2022-02-23 v2 Differential Geometry

Abstract

We establish cosection localization and vanishing results for virtual fundamental classes of derived manifolds, combining the theory of derived differential geometry by Joyce with the theory of cosection localization by Kiem-Li. As an application, we show that the stable pair invariants of hyperk\"{a}hler fourfolds, defined by Cao-Maulik-Toda, are zero.
