Logarithmic Coefficients for Some Classes Defined by Subordination
Copyright policy )Logarithmic Coefficients for Some Classes Defined by Subordination
In this paper, we obtain the sharp and accurate bounds for the logarithmic coefficients of some subclasses of analytic functions defined and studied in earlier works. Furthermore, we obtain the bounds of the second Hankel determinant of logarithmic coefficients for a class defined by subordination, such as the class of starlike functions S*(φ). Some applications of our results, which are extensions of those reported in earlier papers are given here as special cases. In addition, the results given can be used for other popular subclasses.
