Fibrations, unique path lifting, and continuous monodromy
Abstract
Given a path-connected space and , there is essentially only one construction of a map with connected and locally path-connected domain that can possibly have the following two properties: and has the unique lifting property. consists of equivalence classes of paths starting at , appropriately topologized, and is the endpoint projection. For to have these two properties, fibers are necessary and unique path lifting is sufficient. However, always admits the standard lifts of paths. We show that has unique path lifting if it has continuous (standard) monodromies toward a fiber over . Assuming, in addition, that is locally quasinormal (e.g., if is normal) we show that is homotopically path Hausdorff relative to . We show that is a fibration if is locally path connected, is locally quasinormal, and all (standard) monodromies are continuous.
