We study the asymptotic (as n → ∞) zero distribution ofI n ( z , μ , Γ λ ) = (1 ‐ μ ) s n ( z , Γ λ ) ‐ μt n +1 ( z , Γ λ ), where μ ∈ ℂ, s n is n th section, t n is n th tail of the power series of classical Lindelöf function Γ λ of order λ . Our results generalize the results by A. Edrei, E. B. Saff, and R. S. Varga for the case μ = 0 (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
