Initial coefficients for generalized subclasses of bi-univalent functions defined with subordination
This paper is concerned with certain generalized subclasses of bi-univalent functions defined with subordination in the open unit disc . The bounds for the initial coefficients for the functions in these classes are studied. The earlier known results follow as special cases.
Initial Maclaurin coefficient estimates for -pseudo-starlike bi-univalent functions associated with Sakaguchi-type functions
We introduce and study two certain classes of holomorphic and bi-univalent functions associating -pseudo-starlike functions with Sakaguchi-type functions. We determine upper bounds for the Taylor–Maclaurin coefficients and for functions belonging to these classes. Further we point out certain special cases for our results.
Injectivity of sections of convex harmonic mappings and convolution theorems
We consider the class of sense-preserving harmonic functions defined in the unit disk and normalized so that and , where and are analytic in the unit disk.
