Abstract : For classes of functions of m variables satisfying a quadratic inequality involving the L sub 2norm of derivatives up to a given order k, asymptotic estimates are given for the nwidths. They involve upper and lower inequalities of the form ((c/n) to the k/m power) + 0(n to the k/m power) as n approaches infinity, where ce is a positive constant which can be estimated.
