Properties of λ-Pseudo-Starlike Functions of Complex Order Defined by Subordination
Axioms, 2021 In this paper, we defined a new class of λ-pseudo-Bazilevič functions of complex order using subordination. Various classes of analytic functions that map unit discs onto a conic domain and some classes of special functions were studied in dual.
