Article description: (description)
This attribute controls the content of the description and og:description elements. | In topology, Lebesgue's number lemma, named after Henri Lebesgue, is a useful tool in the study of compact metric spaces. It states:
If the metric space $ (X,d) $ is compact and an open cover of $ X $ is given, then there exists a number $ \delta >0 $ such that every subset of $ X $ having diameter... |
