摘要
<正> 1. Let f(z) be an entire function of finite lower order μ. If(?)δ(a,f(j))=1, then (?)pj≤μ, where Pj denotes the number of finite and non-zero deficient values of f(j)(z). More over, every deficient value of f(j)(z) (j=0, ±1, ±2, …; f(0)≡f) is an asymptotic value of f(j)(z) and every deficiency is a multiple of 1/μ.2. If f(z) is an entire function of finite lower order μ, then the series (?){δ(a, f(j)} is convergent.
