| Abstract: | In this paper,the third and fourth coefficient estimations for the subclasses of strongly spirallike functions in the unit disc U of complex plane C are mainly investigated.That is,the third and fourth coefficient estimations for strongly almost spirallike functions of type β and order α and strongly almost starlike functions of order α are mainly studied,and some known results are generalized. |
