### ON CERTAIN MEROMORPHIC P-VALENT FUNCTIONS

#### Abstract

A certain differential operator $D^n$ is introduced for functions of the form $$f(z) = \displaystyle \frac{1}{z^p}+\displaystyle\sum^\infty _{k=0} a_kz^k$$ which are analytic in $E^{\ast } = \{z : 0 \lt |z| \lt 1\}$. The object of the present paper is to give an application of the above operator $D^n$ to the differential inequalities.
