Add to ORKGMaking use of the Ruscheweyh derivatives, we introduce the subclasses T(n,α,λ) (n ∈ {0,1,2,3,...}, −π/2 < α < π/2, and 0 ≤ λ ≤ cos2α) of functions f (z) = z +∑∞k=2 akzk which are analytic in |z | < 1. Subordination and inclusion relations are obtained. The radius of α-spirallikeness of order ρ is calculated. A convolution property and a special member of T(n,α,λ) are also given.
