摘 要: 研究了一类高阶周期系数线性微分方程解的超级、e-型级和相关性等问题,并得到了e-型级与超级之间的一些关系,以及这2种级与系数的精确关系. The problems on the hyper-order,the e-type order,and the dependence of solutions for a class of higher order linear differential equations with periodic coefficients are studied.Furthermore,the followings are obtained:some relations between e-type order and hyper-order,and precise relation between the two kinds of order and coefficients.
