Abstract

In this paper, we find the necessary and sufficient conditions, inclusion relations for Poisson distribution series K(m,z)=z+n=2mn1(n1)!emzn\mathcal{K}(m,z)=z+\sum_{n=2}^\infty \frac{m^{n-1}}{(n-1)!}e^{-m}z^{n} belonging to the subclasses S(k,λ)\mathcal{S}(k,\lambda ) and C(k,λ)\mathcal{C}(k,\lambda ) of analytic functions with negative coefficients. Further, we consider the integral operator G(m,z)=0zF(m,ζ)ζdζ\mathcal{G}(m,z) = \int_0^z \frac{\mathcal{F}(m,\zeta)}{\zeta} d\zeta belonging to the above classes.
