In this paper we obtain coefficient inequalities for the subclass of meromorphic univalent functions with two fixed positive coefficients defined in punctured unit disc. We have studied basic properties such as coefficient estimates, radius of convexity, and closure theorems.
- Univalent function
- fixed coefficients
- distortion theorem
