Özet
Let f (z) = z + a(2)z(2) + a(3)z(3) + ... be an analytic function in the open unit disk. A sharp upper bound is obtained for |a(3) - mua(2)(2)| by using the class M-alpha(lambda)(*) of strongly starlike functions of order beta and type alpha when 0 less than or equal to lambda less than or equal to I and It greater than or equal to 1.
