Abstract: A topological group $ G$ is pro-Lie if $ G$ has small compact normal subgroups $ K$ such that $ G/K$ is a Lie group. A locally compact group $ G$ is an $ L$-group if, for every neighborhood $ U$ of the identity and compact set $ C$, there is a neighborhood $ V$ of the identity such that $ gH{g^{ - 1}} \cap C \subset U$ for every $ g \in G$ and every subgroup $ H \subset V$. We obtain characterizations of pro-Lie groups and make several applications. For example, every compactly generated $ L$-group is pro-Lie and a compactly generated group which can be embedded (by a continuous isomorphism) in a pro-Lie group is pro-Lie. We obtain related results for factor groups, nilpotent groups, maximal compact normal subgroups, and generalize a theorem of Hofmann, Liukkonen, and Mislove [4].
