The Fekete-Szego functional for generalized starlike and convex functions of complex order

New subclasses of analytic functions are defined by using the function f(delta)(z) given by the integral transform f(delta)(z) =f(0)(z)(1+r/1-r)(delta) 1/1-r(2) dr. Bounds for the Fekete-Szego coefficient functional vertical bar a(3) - mu a(2)(2)| for these classes of functions are derived.
