Let P(alpha) be the class of analytic functions p(z) in the open unit disc U with p(0) = 1 and |arg p(z)| < pi/2 alpha (z is an element of U) for some real alpha > 0. The object of the present paper is to discuss some properties of p(z) in the class P(alpha). Furthermore, an example for our results is shown. (C) 2010 Elsevier Ltd. All rights reserved.
