摘要 考虑微分方程f″+Af′+Bf=0,其中A(z),B(z)都是亚纯函数.如果A(z)有一个有穷亏值,当赋予B(z)某些条件时,上述方程的每一个非零解具有无穷级.这些结果将伍鹏程和朱军前期的工作扩展到B(z)的级等于1/2的情形. The authors consider the differential equation f"+Af'+Bf=0,where A(z) and B(z) are meromorphic functions.Assume that A(z) has a finite deficient value.Then under some conditions on B(z),every nonzero solution f to the equation is of infinite order. These results extend the previous work of Wu Pengcheng and Zhu Jun to the case that the order of B(z) is 1/2.
