Description: An extended metric
restricted to any ball (in particular the infinity
ball) is a proper metric. Together with xmetec 14389, this shows that any
extended metric space can be "factored" into the disjoint
union of
proper metric spaces, with points in the same region measured by that
region's metric, and points in different regions being distance ![]() |
