“…The results obtained in this work, are generalization of the results [13] and [42] to more general summability and weighted Orlicz spaces. Similar problems about approximations of the functions by trigonometric polynomials in the different spaces have been investigated by several authors (see, for example, [2], [3], [10][11][12][13][14][15][16][17][18][19][20][21], [23][24][25][26], [33][34][35][36][37][38] , [40] and [42][43][44][45]).…”

“…In [11] under the some conditions related with the sequence (p n ) 1 n=0 Chandra proved satisfactory results about approximation by the N n (f ) and R n (f ) means in in classical Lipschitz classes where 1 p < 1 and 0 < 1. Guven carried and extended the results obtained in [11] to weighted Lipschitz classes where 1 < p < 1 (see, [13,14]). In the Lebesgue space with variable exponent space Guven and Isra…lov investigated the approximation properties of N n (f ) and R n (f ) means for Lipschitz classes in [15].…”

“…These results can be found in the monographs [7,21] for Lebesgue L p spaces. In the weighted Lebesgue and Lorentz spaces with Muckenhoupt A p -weights, some results were obtained in [1][2][3][10][11][12][13][14][15][16][17]22,23].…”
