(General theory of processes
The set of starting times of Brownian excursions from $0$ is a well-known example of a progressive set which does not contain any graph of stopping time. Here it is shown that considering the same set for the excursions from any $a$ and taking the union of all $a$, the corresponding set has the same property and has uncountable sectionsComment:
Other such examples are known, such as the set of times at which the law of the iterated logarithm failsKeywords: Progressive sets
