Abstract
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 di erential operator which is de ned in a punctured unit disk U. By using this criterion, one can nd easily di erent types of meromorphic starlike functions of speci c order.
Keywords
