Bounds for the Second Hankel Determinant of Certain Univalent Functions
The estimates for the second Hankel determinant a_2a_4-a_3^2 of analytic function f(z)=z+a_2 z^2+a_3 z^3+...b for which either zf'(z)/f(z) or 1+zf"(z)/f'(z) is subordinate to certain analytic function are investigated.

New Criteria for Functions in a Class of Meromorphically Strongly Starlike Functions
The authors propose to investigate some new criteria for a certain class of meromorphically strongly starlike functions in the punctured open unit disk. Some intriguing applications that arise as special cases of the main results, which are presented in ...

Some Applications of Differential Subordinations and Superordinations and Sandwich Theoresm
The notions of differential subordinations and superdinations werw introduces by S.S. Miller and P.T. Mocanu. In this paper we present some applications of differential subordination and superdination using function (f(z)zk)α. A sandwich theorem type
