紧凑的空间

Compact space

在数学中,更具体地说在一般的拓扑中,紧凑性是将欧几里德空间的一个子集的概念概括为闭合和界定的属性。 这个概念被广泛应用于更广泛的拓扑空间。 例如,如果从空间采样的任何无限序列的最终无限地经常地任意地接近空间的某个点,则空间依次紧凑。 Bolzano-Weierstrass定理指出,当且仅当它是闭合和有界的时,欧氏空间的一个子集在这个意义上是紧凑的。 示例包括闭合间隔或矩形。 因此,如果在闭合单位间隔中选择无数个点,那些点中的某些点必须任意接近该空间中的某个实数。 例如,1/2,4/5,1/3,5/6,1/4,6/7,...中的一些数字可以任意接近0.同一组点不会有限制 点,打开单位间隔的任意点; 所以打开的单位间隔不紧凑。 欧氏空间本身并不紧凑,因为它没有界限。 In mathematics, and more specifically in general topology, compactness is a property that generalizes the notion of a subset of Euclidean space being closed and bounded. This notion is generalized to more general topological spaces in various ways. For instance, a space is sequentially compact if any infinite sequence of points sampled from the space must eventually, infinitely often, get arbitrarily close to some point of the space. The Bolzano–Weierstrass theorem states that a subset of Euclidean space is compact in this sense if and only if it is closed and bounded. Examples include a closed interval or a rectangle. Thus if one chooses an infinite number of points in the closed unit interval, some of those points must get arbitrarily close to some real number in that space. For instance, some of the numbers 1/2, 4/5, 1/3, 5/6, 1/4, 6/7, … get arbitrarily close to 0. The same set of points would not have, as a limit point, any point of the open unit interval; so the open unit interval is not compact. Euclidean space itself is not compact since it is not bounded.
