Let G be a locally compact Vilenkin group. In this paper we first establish the Hardy-Littlewood-Sobolev theorem on G. Then some boundedness theorems of fractio
In this paper we construct bivariate polynomials attached to a bivariate function, that approximate with Jackson-type rate involving a bivariate Ditzian-Totik
In this paper, we combine the Muskhelishvili's complex variable method and boundary collocation method, and choose a set of new stress function based on the
The "o" saturation theorem and the degree of Lw^p approximation by (0-q'-q) type Hermite-Fejér interpolating polynomials for mean convergence are obtai
