摘要：A number of interesting criteria were given by earlier workers for a normalized analytic function to be in the familiar class 𝔖 * of starlike functions. The main object of the present paper is to extend and improve each of these earlier results. An application associated with an integral operator -1)$"> 𝔉 c ( c > − 1 ) is also considered.
