The estimates on the initial coefficients |a 2 | and |a 3 | for the functions in this subclass are studied. The results obtained in this paper would generalise those already proved by various authors.2010 Mathematics Subject Classifications: 30C45.Keywords and phrases: Bi-univalent functions, Salagean operator, Quasi-subordination, Coefficient estimate, Univalent functions. |
