度量空间度量空间metricspace具有度量的抽象空间,设X是一个集合,若有定义在X×X上的非负实值函数d,满足①d(x,y)≥0,d(x,y)=0x=y;②d(x,y)=d(y,x);③d(x,z)≤d(x,y)+d(y,z),则称(X,d)是度量空间,d称为距离或度量。这是最接近于欧几里得空间的抽象空间。利用度量可很自然地将欧几里得空间上点的邻域、开集、闭集,收敛序列以及连续映射等概念推广到一般度量空间,也能将一致连续的概念推广到度量空间。由于19世纪末集合论产生后,实变函数及泛函分析的发展,需要规定函数间的距离,因而抽象出度量、度量空间的概念,其创始人是M.R.弗雷歇。常见的度量空间有:n维欧几里得空间(Rn,d):Rn={(x1,…,xn)|xi∈R,i=1,2,…,n},d(x,y)=,其中x=(x1,x2,…,xn),y=(y1,y2,…,yn)。希尔伯特空间(l2;d):l2={(x1,x2,…,xn…),其中x=(x1,x2,…),y=(y1,y2,…)∈l2。函数空间(ρ[0,1],d):C[0,1]={f:f为[0,1]上的实值连续函数},对任意f,g∈C[0,1],d(f,g)=max{|f(x)-g(x)|}。x∈[0,1]对度量空间(X,d)可引进拓扑结构,即以包含开球B(x,r)={y∈X|d(x,y)<r}的集为邻域定义拓扑,称为d所诱导的拓扑。
