The universally prestarlike functions of order α ≤ 1 in the slit domain
Λ = C [1;∞) have been recently introduced by S. Ruscheweyh. This notion
generalizes the corresponding one for functions in the unit disk Δ (and other
circular domains in C). In this paper, we obtain the coefficient inequalities
and the Fekete-Szegö inequality for such functions.
