【 摘 要 】

In this paper, we introduce and investigate new subclassesof bi-univalent functions related to shell-like curves connected with Fibonaccinumbers. Furthermore, wend estimates ofrst two coe cientsof functions in these classes. Also, we determine Fekete-Szego inequalitiesfor these function classes.
