Some inequalities exhibiting certain properties of some subclasses of multivalently analytic functions.
The object of the present paper is to derive some inequalities involving multivalent functions in the unit disk. One of our results is an improvement and a generalization of a result due to R. M. Robinson [4].
The purpose of the present paper is to determine lower bounds for , and , where is the generalized normalized error function of the form and its partial sum. Furthermore, we give lower bounds for and , where is the Alexander transform of . Several examples of the main results are also considered.
