Item A subclass of pseudo-type meromorphic bi-univalent functions(Ankara Üniversitesi Fen Fakültesi, 2020-12-31) Alamoush, Adnan; Other; OtherIn this paper, In the present article, a new subclass of pseudo-type meromorphic bi-univalent functions is defined on △={z |:z∈C and 1<|z|<∞}, we derive estimates on the initial coefficient |b₀|, |b₁| and |b₂|. Relevant connections of the new results with various well-known results are indicated. Motivated by the earlier work of (Srivastava, Janani), in the present paper, we introduce a new subclasses of the class Σ′ and the estimates for the coefficients |b₀|,|b₁| and |b₂| are investigated. Some new consequences of the new results are also pointed out.Item On a Janowski formula based on a generalized differential operator(Ankara Üniversitesi Fen Fakültesi, 2020-12-31) Rabha, İbrahim; Other; OtherThe central purpose of the current paper is to consider a set of beneficial possessions including inequalities for a generalized subclass of Janowski functions (analytic functions) which are formulated here by revenues of a generalized Sàlàgean’s differential operator. Numerous recognized consequences of the outcomes are also indicated
