Let such that and A is a dense subset of , and take to be the set of measurable self-maps of I. There exists a residual set such that for each f in , the following hold:
- (1)
The range of f is contained in A, and f is a one-to-one function.
- (2)
For any , the ω-limit set is nowhere dense.
- (3)
The Hausdorff dimension of the ω-limit points is zero.
- (4)
The function f is nowhere continuous.
Any closed set E contained in is an ω-limit set for some measurable function . Moreover, there exists a measurable function such that for any , and closed set , there is a function such that , and .

区间上可测量函数的动态
让 这样 而且A是一个密集的 的子集 ,然后 成为I的可测量的自映射的集合。存在残差集这样对于每一个f in,以下保持:
- (1)
f的范围包含在A中,并且f是一对一的函数。
- (2)
对于任何 ,ω-极限集 无处密集。
- (3)
ω-极限点的Hausdorff维数 是零。
- (4)
函数f在任何地方都不是连续的。
包含在中的任何封闭集E是一些可测函数的ω-极限集。此外,还有一个可测量的功能 这样对于任何 , 和封闭集 ,有一个功能 这样 , 和 。
