Abstract:
We first show that a bounded linear operator T on a real Banach space E is weakly compact if and only if the complex linear operator T on the complex Banach space E_{C} is weakly compact, where E_{C} is a suitable complexification of E and iT' is the complex linear operator on E_{C} associated with T. Next we show that every weakly compact composition operator on real Lipschitz spaces of complexvalued functions on compact metric spaces with Lipschitz involutions is compact.

Abstract:
In this paper we introduce the class of functions regular and multivalent in the and satisfying
where
is
a linear operator.
Coefficient inequalities, distortion bounds, weighted mean and
arithmetic mean of functions for this class have been obtained.
