Web11 mei 2011 · In mathematics, particularly topology, the homeomorphism group of a topological space is the group consisting of all homeomorphisms from the space to itself with function composition as the group operation. Homeomorphism groups are very important in the theory of topological spaces and in general are examples of … WebHomeomorphisms are the isomorphisms in the category of topological spaces —that is, they are the mappings that preserve all the topological properties of a given space.

There is a way to actually "multiply" two maps from an n- sphere into the same space, and make the set of homotopy classes of maps into a group, the nth homotopy group. megabar motherwell
