FEKETE-SZEGO INEQUALITIES FOR CLASSES OF BI-STARLIKE AND BI-CONVEX FUNCTIONS Vol. 3(1) Jan 2015, No. 12, pp. 133-140 JAY M. JAHANGIRI, N. MAGESH AND J. YAMINI

FEKETE-SZEGO INEQUALITIES FOR CLASSES OF BI-STARLIKE AND BI-CONVEX FUNCTIONS Vol. 3(1) Jan 2015, No. 12, pp. 133-140 JAY M. JAHANGIRI, N. MAGESH AND J. YAMINI

We investigate the Fekete-Szegö inequalities for two comprehensive classes of bi-starlike and bi-convex functions.The coefficient bounds obtained in this article, in some cases, improve some of the previously published results.
