Differential subordinations and superordinations for analytic functions defined by S˘al˘agean integro-differential operator [PDF]
, 2019 In this paper we consider the linear operator L n : A → A, L nf (z) = (1 − λ) Dnf (z) + λInf (z) , where Dn is the S˘al˘agean differential operator and In is the S˘ala˘gean integral operator.

New Criteria for Functions in a Class of Meromorphically Strongly Starlike Functions
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria MatematicaThe authors propose to investigate some new criteria for a certain class of meromorphically strongly starlike functions in the punctured open unit disk. Some intriguing applications that arise as special cases of the main results, which are presented in ...

Results on ϕ-like functions involving Hadamard product [PDF]
In this paper, we derive a differential subordination theorem involving convolution of normalized analytic functions. By selecting different dominants to our main result, we find certain sufficient conditions for ϕ−likeness and parabolic ϕ−likeness of ...
