WebWe ﬁrst deﬁne an open ball in a metric space, which is analogous to a bounded open interval in R. De nition 7.18. Let (X,d) be a metric space. The open ball of radius r > 0 and center x ∈ X is the set Br(x) = {y ∈ X: d(x,y) < r}. Example 7.19. Consider R with its standard absolute-value metric, deﬁned in Example 7.3.
