Abstract

In this article, we determined the coefficient inequalities for concave Ces´aro operator which applied on non-concave analytic functions f(z) =P1n=0 an(f)zn, a0 =0, a1 = 2 in an open unit disk U := {z : |z| < 1}. Also we discussed the univalence of this operator by using per-Schwarzian derivative.
