Next by using this differential inequality,some new sufficient conditions for starlike functions and close-to-convex functions with respect to k-symmetric points are obtained,which generalize some existing results.

Using this operator,a subclass Τ_(n+p-1)(η;A,B)() of p-valent analytic functions is investigated,the necessary and sufficient condition of f(z) belonging to Τ_(n+p-1)(η;A,B)() is obtained,some relationships are preserved under the integral operator F_(λ,p),the radius of starlike functions and convex functions are also considered.

Some subclasses R(m,λ,μ,α) of starlike functions are introduced.

This paper studies a new subcategory S* of univalent functions, which is the generalization of star-like functions.

Properties of a subclass of starlike functions of order α;

On the β convexity radius of starlike function with omitting coefficient;

More on a class of analytic functions related to prestarlike functions of orderα;

The integral operator Pσλf(z) was used to describe starlike function,convex function close-to-convex function and the new subclass of quasi convex function and to establish inclusion relations.

This paper continues to study a family analytic functions A of linear homeomorphic and starlike functions in [1] introduced.
