Abstract—We construct representations of the quantum algebras \({{U}_{{q,{\mathbf{q}}}}}(gl(n))\) and \({{U}_{{q,{\mathbf{q}}}}}(sl(n))\) which depend on \(n(n - {{1)} \mathord{\left/ {\vphantom {{1)} 2}} \right. \kern-0em} 2} + 1\) deformation parameters \(q,{{q}_{{ij}}}\) (\(1 \leqslant i < j \leqslant n\)) which is the maximal possible number in the case of \(GL(n).\) The representations act on the space of formal power series of \(n(n - {{1)} \mathord{\left/ {\vphantom {{1)} 2}} \right. \kern-0em} 2}\) non-commuting variables which generate quantum flag manifolds of \(G{{L}_{{q{\mathbf{q}}}}}(n),\)\(S{{L}_{{q{\mathbf{q}}}}}(n).\) For \(n = 4\) we consider in detail the multiparameter quantum Minkowski space-time.
