The purpose of the present paper is to investigate various inclusion relationships between several classes of analytic functions defined by subordination. Many interesting applications involving the well-known classes of functions defined by linear operators are also considered.
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.
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.
