SHARP INEQUALITIES FOR UNIVALENCE OF MEROMORPHIC FUNCTIONS IN THE PUNCTURED UNIT DISK

A new class of meromorphic functions f that are univalent in the punctured unit disk U* = z : 0 < |z| < 1 is introduced. This class is denoted by MU and consisting of functions f defined by |1 + f' (z)/f (2)(z)| < 1 and zf (z) [not equal to] 0, whenever z [member of] U = z : |z| < 1...
