| 1 | ON N-WIDTHS OF SOME PERIODIC CONVOLUTION CLASSES IN ORLICZ SPACES显示文摘In this paper we extend the some accurate results on n-width of Sobolevclass W_∞~γ in L_p spaces to Orlicz spaces,and establish the correspondingresults for dual cases. | Wu Garidi (Inner Mongolia Normal University,China) | 1998 | Analysis in Theory and Applications1998，14，3： | 10 |
| 2 | ON APPROXIMATION BY RECIPROCALS OF POLYNOMIALS WITH POSITIVE COEFFICIENTS IN ORLICZ SPACES显示文摘This paper discusses the approximation by reciprocals of polynomials with positive coefficients in Orlicz spaces and proved that if f(x) ∈ LM*[0,1], changes its sign at most once in (0,1), then there exists x0 ∈ (0,1) and a polynomial Pn ∈Πn(+) such that f (x) -Pn (x)x-x0 M ≤ Cω( f,n-1/2 )M, where Πn(+) indicates the set of all polynomials of degree n with positive coefficients. | Xiaoli Wang Ran Huo Garidi Wu | 2008 | Analysis in Theory and Applications2008，24，4： | 5 |
| 3 | THE JACKSON THEOREM IN B_a SPACES显示文摘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, | Wu Garidi (Inner Mongolia Normal University,China) | 1996 | Analysis in Theory and Applications1996，12，2： | 3 |

| 14 | On Approximation by Reciprocals of Polynomials with Positive Coefficients显示文摘In order to study the approximation by reciprocals of polynomials with real coefficients, one always assumes that the approximated function has a fixed sign on the given interval. Sometimes, the approximated function is permitted to have finite sign changes, such as l(l ≥ 1) times. Zhou Songping has studied the case l = 1 and l ≥ 2 in Lp spaces in order of priority. In this paper, we studied the case l ≥ 2 in Orlicz spaces by using the function extend, modified Jackson kernel, Hardy-Littlewood maximal function, Cauchy-Schwarz inequality, and obtained the Jackson type estimation. | Lian Hai Garidi Wu | 2013 | Analysis in Theory and Applications2013，29，2： | 1 |
