Abstract |
|
|
In this paper, we define a generalized class of starlike
functions with negative coefficients and obtain coefficient
estimates, distortion bounds, closure theorems and extreme
points. Further we obtain modified Hadamard product, radii of
close-to-convex, starlikeness and convexity for functions
belonging to this class. Furthermore neighborhood results are
discussed.
Key words:
Univalent functions, convex functions, starlike
functions,
 -neighbourhood,
inclusion relations, Hadamard product, Wright generalized
hypergeometric functions.
