The Logarithmic Coefficient Inequality for Close–to–convex Functions of Complex Order

We prove that if n 2 for each close-to-convex functions of complex order b in S whose n− th logarithmic coefficients γn satisfies |γn| An−1 logn, where A is an absolute constant. Mathematics subject classification (2010): 30C45.

ACTA UNIVERSITATIS APULENSIS No 9/2005 SOME SUBCLASSES OF n -UNIFORMLY CLOSE TO CONVEX FUNCTIONS WITH NEGATIVE COEFFICIENTS

In this paper we define some subclasses on n-uniformly close to convex functions with negative coefficients and we obtain necessary and sufficient conditions and some other properties regarding this classes. 2000 Mathematics Subject Classification: 30C45
