Nonabelian Bundle Gerbes, their Differential Geometry and Gauge Theory

arXiv:hep-th/0312154 · doi:10.1007/s00220-004-1220-6

Abstract

Bundle gerbes are a higher version of line bundles, we present nonabelian bundle gerbes as a higher version of principal bundles. Connection, curving, curvature and gauge transformations are studied both in a global coordinate independent formalism and in local coordinates. These are the gauge fields needed for the construction of Yang-Mills theories with 2-form gauge potential.
