Finite covering map
WebMar 6, 2024 · In topology. In topology, a map is a branched covering if it is a covering map everywhere except for a nowhere dense set known as the branch set. Examples include the map from a wedge of circles to a single circle, where the map is a homeomorphism on each circle.. In algebraic geometry. In algebraic geometry, the term branched covering is … Web5. The niceness condition you want is on the action, not on the space X. Specifically, you want to have that X → X / G is a principal G -bundle, so that we have a Serre spectral …

WebMar 9, 2024 · Inspired by the work of W. Thurston on postcritically finite maps, he introduced deformation spaces into holomorphic dynamics , . The cornerstone of W. Thurston’s approach to postcritically finite maps is the pull-back map on the Teichmüller space induced by the branched cover. A. Epstein used the pull-back map to define … WebFinite extensions of complex commutative Banach algebras are naturally related to corresponding finite covering maps between the carrier spaces for the algebras. In the case of function rings, the finite extensions are induced by the corresponding finite covering maps, and the topological properties of the coverings are strongly reflected in ...
