Some properties of subclass of multivalent functions associated with a generalized differential operator

Abstract

Abstract In this paper, the new subclass $$\mathcal {S}^n_{b,\lambda ,\delta ,p} ({\alpha })$$ S b , λ , δ , p n ( α ) of a linear differential operator’s $$\mathcal {N}_{\lambda ,\delta ,p}^{n}f(\zeta )$$ N λ , δ , p n f ( ζ ) associated with multivalent analytical function has been introduced. Further, the coefficient inequalities, extreme points for the extremal function, sharpness of the growth and distortion bounds, partial sums, starlikeness, and convexity of the subclass is investigated.
