Branched covering map
WebLet be a topological space. A covering of is a continuous map : such that there exists a discrete space and for every an open neighborhood, such that () = and : is a homeomorphism for every .Often, the notion of a covering is used for the covering space as well as for the map :.The open sets are called sheets, which are uniquely determined … WebWith that said, note the following property of maps which lets us know that connecting maps via their points of intersection yields another map (under a certain assumption). Pasting …

Then f is a locally branched covering if and only if for each p E M there is an open neighborhood Uc M containing p, such that f I U-{p} -f(U) -f(p) exhibits U-p as an m-sheeted covering space for some integer m. We let Of(p) = m - 1 and call this the branching order of the mapping f at p.

WebExample 2.1. The Poincar´e homology sphere M can be viewed as a 5-fold covering of S3 branched along the trefoil K2,3, or as a 3-fold cover branched along the (2,5) torus knot K2,5 of also as a 2-fold cover branched along the (3,5) torus knot K3,5. Thus we can see Mas a correspondence K2,3 ⊂S3 ←M→S3 ⊃K2,5, or as K2,5 ⊂S3 ←M→S3 ...
