Some Properties for Certain Subclasses of Spiral-Like and Robertson Analytic Functions.

Making use of the definition of subordination, we introduce certain subclasses of spiral-like and Robertson functions in the open unit disk and study some important results such as convolution results, coefficients estimate, subordination properties and Fekete-Szego problems for these subclasses. Further, some known and new outcomes which follow as special cases of our outcomes are also mentioned. [ABSTRACT FROM AUTHOR]
