A CRITICAL STUDY OF MEROMORPHIC STARLIKE FUNCTIONS

An attempt has been made to introduce a new criterion to make it possible to change meromorphic analytic function into a meromorphic starlike function of particular order. This criterion is based on a dierential operator which is dened in a punctured unit disk U. By using this criterion, one can nd easily dierent types of meromorphic starlike functions of specic order.
