摘要:In this paper, the authors investigate the iterated exponent of convergence of zeros of f (j)(z) - ?(z) (j = 0, 1, 2, ?), where f is a solution of some second-order linear differential equation, ?(z) ? 0 is an entire function satisfying σp+1(ell;) < σp+1(f) or i(ell;) < i(f ) (p ? N). We obtain some results which improve and generalize some previous results in (Chen in Acta Math. Sci. Ser. A 20(3):425-432, 2000; Chen and Shon in Chin. Ann. Math. Ser. A 27(4):431-442, 2006; Tu et al. in Electron. J. Qual. Theory Differ. Equ. 23:1-17, 2011) and provide us with a method to investigate the iterated exponent of convergence of zeros of f (j)(z) - ?(z) (j = 0, 1, 2, ?). ? 2013 Tu et al.
