Abstract
Let G be a simple connected domain on complex plane such that ???? := @G where ???? is a Carleson curve. In this work, we investigate the rate of approximation by De La Vall ee Poussin mean constructed via p ???? " Faber series in the proper subclass of weighted generalized grand Smirnov classes Ep); !
