Since in a metric space, a compact set is closed, the condition remains necessary. However, it's not sufficient. Consider E = R with the usual metric, P n := δ n and P any probability measure. Then for each compact K, P n ( K) = 0 for n ...

Many important results in asymptotic analysis can be derived from them. Below we derive several of these results, both because of their importance in future discussion and as exercises to practice the use of the Portmanteau theorem.
