摘要:
In this paper, we construct a new Roper-Suffridge extension operator
Φrn, β1,… , βn(f)(z) = F(z) = ((rf( z1/r /z1 )β1 z1, (rf( z1/r /z1 )β2 z2, … , (rf( z1/r /z1 )βnzn)′,
where f is a normalized locally biholomorphic function on the unit disc D, r = sup{|z1| : z =(z1, … , zn) ∈Ω}, β1 ∈ [0, 1], 0≤ βk ≤ β1, k = 2, … , n, then we prove it can preserve the property of spirallikeness of type , almost starlikeness of order and starlikeness of order α on bounded complete Reinhardt domain Ω, respectively.
