Query: Gruss Type Discrete Inequalities in Normed Linear Spaces, Revisited   Some sharp inequalities of Gruss type for sequences of vectors in real or
complex normed linear spaces are obtained. Applications for the discrete
Fourier and Mellin transform are given. Estimates for polynomials with
coefficients in normed spaces are provided as well.
