چکیده
|
In this paper, we introduce a new subclass of analytic and te-univalent functions in the open unit disc associated with the operator t λ,p,q ζ , which is defined by using the (p,q)-derivative. we obtain the coefficient estimates and fekete–szegő inequalities for the functions belonging to this class.the various results presented in this paper would generalize and improve those in related works of several earlier authors.
