Abstract:

Suppose that X is a complex Banach space with the norm {double pipe} · {double pipe} and n is a positive integer with dim X ≥ n ≥ 2. In this paper, we consider the generalized Roper-Suffridge extension operator Φn, β2, γ2,...,β n+1, γ n+1 (f) on the domain Ω p1, p2,....,pn+1 defined by with pj > 1 (j = 1, 2,..., n+1), the linearly independent family {x1, x2,...,xn} ⊂ X and {x1*, x2*,...,xn*} ⊂ X* satisfy xj*(xj) = {double pipe}xj{double pipe} = 1 (j = 1,2,..., n) and xj* (xk) = 0 (j ≠ k), and we choose the branch of the power functions such that j = 2,..., n + 1. We prove that the operator Φn, β2, γ2,....,β n+1, γ n+1 (f) preserves almost spirallike mapping of type β and order α or spirallike mapping of type β and order α on Ω p1, p2,....,pn+1 for some suitable constants βj, γj. © 2009 Science in China Press and Springer Berlin Heidelberg.
