【 摘 要 】

References(13)In this paper, we investigate the exponent of convergence of the zero-sequence of solutions of the second order linear differential equation$f''+(¥sum_{j=1}^{l}Q_j(z)e^{P_j(z)})f=0,$where Pj (z) (j= 1,2, ..., l ≥ 3) are polynomials of degree n ≥ 1, Qj (z) are entire functions of order less than n, and obtain some results which improve and generalize the previous results in [8, 9, 13].
