MEROMORPHIC MULTIVALENT FUNCTIONS WITH POSITIVE AND FIXED SECOND COEFFICIENTS

- S. Owa, H. Darwish, M. Aouf
- Mathematics
- 1 September 1997

In this paper we consider the class (p; A, B) consisting of regular and p-valent functions in the punctured disc D = {z : 0 (p; A, B). Also we have shown that the class (p; A, B) is closed under… Expand
