Some Theorems of Approximation Theory in Weighted Smirnov Classes with Variable Exponent

Let G. C be a Jordan domain with rectifiable Dini smooth boundary G. In this work, we investigate approximation properties of matrix transforms constructed via Faber series in weighted Smirnov classes with variable exponent. Moreover, direct and inverse theorems of approximation theory in weighted Smirnov classes with variable exponent are proved and some results related to constructive characterization in generalized Lipschitz classes are obtained.
