ON THE PROPERTIES OF A CERTAIN SUBCLASS OF CLOSE-TO-CONVEX FUNCTIONS

  • Fund Project:
  • In the present paper, we introduce an interesting subclass Ksp(h) of analytic functions in the open unit disk U. For functions belonging to the class Ksp(h), basic properties such as the coefficient bounds, the distortion and growth theorems are derived. The results presented here would provide extensions of those given by Q.-H. Xu et al.[2].
