Certain Coefficient Bounds for p-Valent Functions
International Journal of Mathematics and Mathematical Sciences, 2007 In the present paper, the authors obtain sharp bounds for certain subclasses of p-valent functions. The results are extended to functions defined by convolution.

Subordination properties of P-valent functions defined by integral operators [PDF]
International Journal of Mathematics and Mathematical Sciences, 2006 By applying certain integral operators to P-valent functions we define a comprehensive family of analytic functins. The subordinations properties of this family is studied, which in certain special cases yield some of the previously obtained results.

Inclusion Properties for Classes of p-Valent Functions
Journal of Function SpacesMaking use of a differential operator, which is defined here by means of the Hadamard product, we introduce classes of p-valent functions and investigate various important inclusion properties and characteristics for these classes.
