Abstract
. In this paper, a brief study of certain properties of bounded turning functions is carried out. Furthermore, bound to the famous Fekete - Szego functional H 2 (1) = | a 3 − ta 22 | , with t real and the Second Hankel Determinant H 2 (2) = | a 2 a 4 − a 23 | for functions of bounded turning of order β associated with Salagean differential operator are obtained using a succinct mathematical approach.
