Abstract: The various properties of several subclasses S_p,k^l,m(\alpha_1;h),\\ K_p,k^l,m(\alpha_1;h), K_p,k^l,m(\lambda;\alpha_1;h), C_p,k^l,m(\alpha_1;h) and QC_p,k^l,m(\lambda;\alpha_1;h) of multivalent analytic functions are investigated. Sufficient condition for the subclass C_p,k^l,m(\alpha_1;h) is provided, and the inclusion relationships, integral representations, convolution properties for other function classes are proved.
