Considering a new subclass of m-fold symmetric analytic bi-univalent functions, we determine estimates the coefficient bounds for the Taylor-Maclaurin coefficients |a_{m+1}| and |a_{2m+1}| of the functions in this class. ...

In this paper, we introduce and investigate a new subclass of the a-nalytic and bi-univalent functions in the open unit disk in the complex plane. For the functions belonging to this class, we obtain estimates on the first ...

In this paper, we introduce and investigate new subclasses of bi-univalent functions related to k-Fibonacci numbers. Furthermore, we nd estimates of first two coecients of functions in these classes. Also, we obtain the ...

In this paper a new subclass of uniformly spirallike functions is defined and several properties like coefficient estimate, closure theorems, distortion theorems, radii of starlikeness and convexity are studied.
