Probabilistic linear(N,δ)-widths and p-average linear N-widths of Sobolev space W_2~τ(T),equipped with a Gaussian probability measure μ,are studied in the metric of S_q(T)(1 q oo),and determined the asymptotic equalities:and where 0p∞,δ∈(0,1/2],ρl,and Sq(T) is a subspace of L_1(T),in which the Fourier series is absolutely convergent in l_q sense. 相似文献
