Abstract
The object of the present paper is to study certain subclasses Jp* (a,b,σ) and Cp(a,b,σ) of analytic p-valent functions, and obtain coefficient bounds and distortion properties for functions belonging to these subclasses. Further results include distortion inequalities and radii of close-to-convexity, starlikeness and convexity for these classes of functions.
