Coefficient estimates for the class of quasi q-convex functions

In this paper we introduce and investigate the class of Pq(λ, β, A, B), which is called quasi q-starlike andquasi q-convex with respect to the values of the parameter λ. We give coefficient bounds estimates and the results forthe main theorem.
