A Class of Complex-valued Harmonic Functions Defined by Dziok-Srivastava Operator
Keywords:
Harmonic functions, Hypergeometric functions, Dziok-Srivastava operator, extreme points, integral operatorAbstract
The Dziok-Srivastava [6] operator introduced in the study of analytic functions and associated with generalized hypergeometric functions has been extended to harmonic mappings [2, 12]. Using this operator we introduce a subclass of the class of complex-valued harmonic univalent functions
where
is the analytic part and
is the co-analytic part of
in
<
. Coefficient bounds, extreme points, inclusion results and closure under an integral operator for this class are obtained.
