WebA Seifert–Van Kampen theorem describes the fundamental group of a space in terms of the fundamental groups of the constituents of a covering and the configuration of connected components of the covering. Here we provide the combinatorial part of such a theorem for the most general sort of coverings.

WebVan Kampen's theorem (0.00) Let X be a topological space and let U, V ⊂ X be open subsets such that U ∩ V is nonempty and path-connected. Let x ∈ U ∩ V be a basepoint. Then π 1 ( X, x) = π 1 ( U, x) ⋆ π 1 ( U ∩ V, x) π 1 ( V, x). (1.12) Here, A ⋆ C B denotes the amalgamated product. WebScopri la vasta ed esclusiva collezione di Morren Galleries Utrecht.
