【 摘 要 】

We extend the results presented by Xh. Z. Krasniqi (Slight extensions of some theorems on the rate of pointwiseapproximation of functions from some subclasses of Lp. Acta Comment. Univ. Tartu. Math., 2013, 17, 89–101) and W. Lenski andB. Szal (Approximation of functions belonging to the class Lp(w) by linear operators. Acta Comment. Univ. Tartu. Math., 2009,13, 11–24) to the case when a conjugate function depends on r and where in the measures of estimations r-differences of the entriesare used.
