| Abstract: | The main aim of this paper is to discuss the third Hankel determinants for three classes: (S^*) of starlike functions, (mathcal {K}) of convex functions and (mathcal {R}) of functions whose derivative has a positive real part. Moreover, the sharp results for twofold and threefold symmetric functions from these classes are obtained. |
