A. Abdesselam et M. Tahiri, GENERALIZED CONNECTION FORMALISM AND BRST COHOMOLOGY STRUCTURE FOR BFTHEORIES, Modern physics letters A, 13(23), 1998, pp. 1837-1844
The non-Abelian BF theories in arbitrary dimensions are studied in a g
eneralized connection formalism. This gives rise to the off-shell nilp
otent BRST operator which permits construction of BRST exact quantum a
ction. A set of operators satisfying the descent equations is derived
from the generalized curvature; but it cannot lead to nontrivial obser
vables. An off-shell superalgebra of Wess-Zumino type, containing the
vector supersymmetry and the BRST symmetry, is also derived.
