| Description: One of the important properties of covering maps is that any path 𝐺 in the base space "lifts" to a path 𝑓 in the covering space such that 𝐹 ∘ 𝑓 = 𝐺, and given a starting point 𝑃 in the covering space this lift is unique. The proof is contained in cvmliftlem1 35971 thru cvmliftlem15 35984. (Contributed by Mario Carneiro, 16-Feb-2015.) |
