Abstract

For any principal bundle P, one can consider the subspace of the space of connections on its tangent bundle TP given by the tangent bundle Tscript A sign of the space of connections . script A sign on P. The tangent gauge group acts freely on Tscript A sign. Appropriate BRST operators are introduced for quantum field theories that include as fields elements of Tscript A sign, as well as tangent vectors to the space of curvatures. As the simplest application, the BRST symmetry of the so-called BF-Yang-Mills theory is described and the relevant gauge fixing conditions are analyzed. A brief account on the topological BF theories is also included and the relevant Batalin-Vilkovisky operator is described.
