Inclusion relations involving certain classes of p–valent meromorphic functions with positive coefficients based on a linear operator

In this paper two classes M_p(γ, a, c, β) and N_p(γ, a, c, β, μ) of p–valent meromorphic functions of the form involving a linear operator are defined. Coefficient inequalities and extreme points for functions belonging to these classes are obtained. Inclusion relations of these classes using δ–neighbourhood N^δ_p (I) are also found. Further, using subordinate characterization inclusion relation between M_p(γ, a, c, β) and N_p(γ, a, c, β, μ) is also obtained.
