These coordinates correspond to the local ones of the flag manifold. This realization provides us with a guide to construct the free field realization for the quantum affine superalgebra Uq^(sl(M+1|N+1)) at arbitrary level.7pages, AMS-Tex, no figureQuantum AlgebraHigh Energy Physics - Theoryq-differential operator representation of the quantum superalgebra Uq(sl(M+1|N+1))text
