中文摘要:

Let M(u) be an N-function, Lr(f, x) and Kr(f, x) are Bak operator and Kantorovich operator, WM(Lr(f)) and WM(Kr(f)) are the Sobolev-Orlicz classes defined by Lr(f, x), Kr(f, x) and M(u). In this paper we give the asymptotic estimates of the n-K widths dn(WM(Lr(f)), L2[0, 1]) and dn(WM(Kr(f)), L2[0, 1]).

Let M(u) be an N-function, Lr(f, x) and K_r(f, x) are Bak operator and Kantorovich operator, WM(Lr(f)) and WM(Kr(f)) are the Sobolev-Orlicz classes defined by Lr(f, x), Kr(f, x) and M(u). In this paper we give the asymptotic estimates of the n-K widths dn(WM(Lr(f)), L2[0, 1]) and d_n(WM(Kr(f)), L2[0, 1]).
