Braun Space cover Standard. Space cover Standard. Zoom. Loading zoom. This is the kind of basic material that ought to have been in standard textbooks on fundamental groups for the last fifty years. In mathematics , more specifically algebraic topology , a covering map also covering projection is a continuous function p [1] from a topological space , C , to a topological space, X , such that each point in X has an open neighbourhood evenly covered by p as shown in the image ; the precise definition is given below. A covering space is a universal covering space if it is simply connected. The homeomorphic copies in C of an evenly covered neighborhood U are called the sheets over U. This article needs additional citations for verification. Empfehlen Sie dieses Produkt per E-Mail weiter. However, when the deck transformation group is a topological group whose topology is not discrete , difficulties arise. Armstrong on the fundamental groups of orbit spaces wrote: Some New Additions Selected randomly from new stock added. Thus a covering map p: If the space X carries some additional structure, then its universal cover usually inherits that structure:. Medi-King ist Ihr Zugang zur Medizintechnik. Since coverings are local homeomorphismsa covering of a topological n - manifold is an n -manifold. A covering space of X is a topological space C together with a continuous surjective map.

Moreover, C n T is a free Z G -module with free Z G -basis given by representatives of G -orbits kung fu pand 2 n -cells in T.

Covering spaces play an important role in homotopy theory , harmonic analysis , Riemannian geometry and differential topology. The special open neighborhoods U of x given in the definition are called evenly covered neighborhoods. One can prove that the covering space is second-countable from the fact that the fundamental group of a manifold is always countable.

In particular, the cardinality of the fiber over x is equal to the cardinality of F and it is called the degree of the cover p: Articles needing additional references from June All articles needing additional references Articles needing cleanup from September All pages needing cleanup Cleanup tagged articles with a reason field from September Wikipedia pages needing cleanup from September Unsourced material may be challenged and removed. This causes problems in applications, and is formalized by the notion of a covering space. The universal cover of the space X can be constructed as a certain space of paths in the space X. space cover
