abstract: 'This paper makes use of multiplicative vector fields on Lie groupoids to model infinitesimal symmetries of $S^1$-bundle gerbes. It is shown that a connective structure on a bundle gerbe gives rise to a natural horizontal lift of multiplicative vector fields to the bundle gerbe, and that the 3-curvature p... |
