Abstract
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 of functions in these subclasses are obtained. Fin ally, several applications involving an integral operator and certain fractional calculus operators are also considered. (C) 1997 Academic P ress.
