| In this paper, we introduce new subclasses $S_{p,q,\lambda}^{m,j,l}[A,B;\gamma]$ and $H_{p,q,\lambda}^{m,j,l}(\alpha,\beta)$ of certain p-valent analytic functions defined by a generalized differential operator. Majorization properties for functions belonging to the classes $S_{p,q,\lambda}^{m,j,l}[A,B;\gamma]$ and $H_{p,q,\lambda}^{m,j,l}(\alpha,\beta)$ are investigated. Also, we point out some new or known consequences of our main results. |
