摘要：In this paper, we deal with the relationship between the small function and the derivative of solutions of higher order linear differential equations f ( k ) + A k − 1 f ( k − 1 ) + ⋯ + A 0 f = 0 ( k ≥ 2 ) , where A j ( z ) ( j = 0 , 1 , … , k − 1 ) are entire functions or meromorphic functions. The theorems of this paper improve the previous results given by Chen, Belaïdi, Liu. MSC:34M10, 30D35.
