Objective B-Fields and a Hitchin-Kobayashi Correspondence
Shuguang Wang
A simple trick invoking objective B-fields is employed to refine the concept of characteristic classes for twisted bundles. Then the objective stability and objective Einstein metr…

Orientability and real Seiberg-Witten invariants
Gang Tian, Shuguang Wang
We investigate Seiberg-Witten theory in the presence of real structures. Certain conditions are obtained so that integer valued real Seiberg-Witten invariants can be defined. In ge…

Gerbes, Holonomy Forms and Real Structures
Shuguang Wang
We study geometry on real gerbes in the spirit of Cheeger-Simons theory. The concepts of adaptations and holonomy forms are introduced for flat connections on real gerbes. Their re…
