On neighborhoods of two new subclasses of multivalent functions with negative coefficients
In this paper, we introduce two new subclasses of p-valent analytic functions defined by means of fractional derivative of order ? ? . We obtained the various results including coefficient bounds and distortion inequalities for these function classes. Furthermore, we determine some inclusion relations for the (n,p,?) ( n , p , ? ) -neighborhoods of a family of p-valent analytic functions with negative coefficients which is defined by means of a certain nonhomogeneous CauchyEuler differential equation.
