Abstract

In this paper, we introduce an N×NN\times N matrix ϵabˉ\epsilon^{a\bar{b}} in the quantum groups SUq(N)SU_{q}(N) to transform the conjugate representation into the standard form so that we are able to compute the explicit forms of the important quantities in the bicovariant differential calculus on SUq(N)SU_{q}(N), such as the qq-deformed structure constant CIJ K{\bf C}_{IJ}^{~K} and the qq-deformed transposition operator Λ\Lambda. From the qq-gauge covariant condition we define the generalized qq-deformed Killing form and the mm-th qq-deformed Chern class PmP_{m} for the quantum groups SUq(N)SU_{q}(N). Some useful relations of the generalized qq-deformed Killing form are presented. In terms of the qq-deformed homotopy operator we are able to compute the qq-deformed Chern-Simons Q2m1Q_{2m-1} by the condition dQ2m1=PmdQ_{2m-1}=P_{m}, Furthermore, the qq-deformed cocycle hierarchy, the qq-deformed gauge covariant Lagrangian, and the qq-deformed Yang-Mills equation are derived.
