Abstract

In this paper, from the qq-gauge covariant condition we define the qq-deformed Killing form and the second qq-deformed Chern class for the quantum group SUq(2)SU_{q}(2). Developing Zumino's method we introduce a qq-deformed homotopy operator to compute the qq-deformed Chern-Simons and the qq-deformed cocycle hierarchy. Some recursive relations related to the generalized qq-deformed Killing forms are derived to prove the cocycle hierarchy formulas directly. At last, we construct the qq-gauge covariant Lagrangian and derive the qq-deformed Yang-Mills equation. We find that the components of the singlet and the adjoint representation are separated in the qq-deformed Chern class, qq-deformed cocycle hierarchy and the qq-deformed Lagrangian, although they are mixed in the commutative relations of BRST algebra.
