普遍性的概念出现在数学的各个领域。在[6]中给出了普遍性的一般定义。设X,Y是拓扑空间,Tj:X → Y,j ∈ I是连续映射.则称元素x ∈ X关于族{Tj,j ∈ I}是泛的,如果集合{Tjx:j ∈ I}在Y中稠密。许多不同性质的普遍物体是已知的,请参阅一篇出色的调查论文[6]。我们回顾Birkhoff的一个结果[4]。他证明了存在一个整函数f,使得对于每个整函数g,都存在一个复数序列{an},使得f(z + an)−→ n→∞ g(z)
The notion of the universality appears in various fields of mathematics. A general definition of the universality is given in [6]. Let X and Y be topological spaces and Tj : X → Y , j ∈ I, be continuous mappings. Then an element x ∈ X is called universal with respect to the family {Tj , j ∈ I} if the set {Tjx : j ∈ I} is dense in Y . Many universal objects of various nature are known, see an excellent survey paper [6]. We recall a result of Birkhoff [4]. He proved that there exists an entire function f such that for every entire function g there exists a sequence of complex numbers {an} such that f(z + an) −→ n→∞ g(z)
