Pseudo starlike functions involving convex combination of two starlike functions

Journal of Interdisciplinary Mathematics
In this paper, we introduce a new class of functions involving a familiar analytic characterization that was used to obtain sufficient conditions for starlikeness. We have discussed the impact of the convex combination of two starlike functions. The results obtained here extend or unify the various other well-known and new results.

Certain Results on Starlike and Parabolic Starlike Functions

International Journal of Open Problems in Computer Science and Mathematics, 2015
Using the technique of differential subordination, we obtain certain results for starlike and parabolic starlike functions involving the differential operator zf ′(z) f(z) ( 1 + α zf ′′(z) f ′(z) ) . We study the above operator for multivalent functions and also conclude some results for univalent functions.

\(M\)-almost-starlike functions

1993
Let \(S\) be the usual class of normalized univalent functions in the unit disk \(\Delta\). Given \(M>1\) let \(S(M)= \{f\in S: | f(z)|< M\) for all \(z\in\Delta\}\) and let \(M(S)= \{f\in S: f(z)/M\in f(\Delta)\) for all \(z\in \Delta\}\). The author calls such functions \(M\)-almost starlike and proves that \(\varphi\in S\) is in \(M(S)\) if and only
