The author aims at finding certain conditions on a, b and c such that the normalized is in certain subclasses of analytic functions. A particular operator acting on F (a, b; c; z) is also discussed.
In this paper our aim is to deduce some Turán type inequalities for q-hypergeometric and q-confluent hypergeometric functions. In order to obtain the main results we apply the methods developed in the case of classical Kummer and Gauss hypergeometric functions.
