As everyone knows,the classical Jackson theorem in approximation theory was generalized in Lp spaces by R.A.Devore.In this paper,we proved the Jackson theorem in B,spaces which introduced by Ding Xia Xi,
In this paper we extend the some accurate results on n-width of Sobolev class W ∞ t in Lp spaces to Orlicz spaces, and establish the corresponding results for dual cases.
