Abstract

For function   of Bazilevic type, initial coefficients  for certain generalized class of analytic functions involving logistic sigmoid function are obtained. Further, the Fekete-Szego functional  is also considered for functions belonging to the said class of analytic functions. Several other results follow as simple consequences.

Analytic starlike convex Bazilevic sigmoid function.
