Abstract: |
In this paper, some subclasses of meromorphic univalent functions in the unit disk  are extended. Let  denote the class of normalized univalent meromorphic functions  in with a simple pole at  . Let  be a function with positive real part on with  ,  which maps onto a region starlike with respect to  which is symmetric with respect to the real axis. The class  consists of functions  satisfying The class  consists of functions satisfying The bounds for  and some initial coefficients of in and are obtained.
