Approximation in Smirnov classes with variable exponent
Daniyal M. İsrafilov, Ahmet Testici · Complex Variables and Elliptic Equations · 2015
In this work, the inverse problem of approximation theory in the variable exponent Smirnov classes of analytic functions, defined on the Jordan domains with a Dini-smooth boundaries, is studied. First, for this purpose, an inverse theorem in the variable exponent Lebesgue spaces of periodic functions is obtained. Later, using the special linear operators, this inverse theorem to the variable exponent Smirnov classes of analytic functions is moved.
