Abstract
Certain subclasses π~p~(j, Ξ±), β¬οΈ~p~(j, Ξ±) and π’~p,b~(j, Ξ±) of multivalent functions in the unit disk are introduced. The object of the present paper is to derive some properties of functions belonging to the classes π~p~(j, Ξ±), β¬οΈ~p~(j, Ξ±), or π’~p,b~(j, Ξ±). Further, generalizations of results for certain multivalent functions by M. NUNOKAWA, S. OWA and H. SAITOH [9], and by R. SINGH and S. SINGH [13] are shown.

The authors introduce and study three novel subclasses of analytic and p-valent functions with negative coefficients. In addition to finding a necessary and sufficient condition for a function to belong to each of these subclasses, a number of other potentially useful properties and characteristics
