Manifold decomposition — In topology, a branch of mathematics, a manifold M may be decomposed or split by writing M as a combination of smaller pieces. When doing so, one must specify both what those pieces are and how they are put together to form M. Manifold… … Wikipedia
E₈ manifold — In mathematics, the E8 manifold is the unique compact, simply connected topological 4 manifold with intersection form the E 8 lattice. The E8 manifold was discovered by Michael Freedman in 1982. Rokhlin s theorem shows that it has no smooth… … Wikipedia
Orientability — For orientation of vector spaces, see orientation (mathematics). For other uses, see Orientation (disambiguation). The torus is an orientable surface … Wikipedia
Lefschetz fixed-point theorem — In mathematics, the Lefschetz fixed point theorem is a formula that counts the number of fixed points of a continuous mapping from a compact topological space X to itself by means of traces of the induced mappings on the homology groups of X . It … Wikipedia
Hauptvermutung — The Hauptvermutung (German for main conjecture) of geometric topology is the conjecture that every triangulable space has an essentially unique triangulation. It was originally formulated in 1908, by Steinitz and Tietze.This conjecture is now… … Wikipedia
Triangulation (topology) — In mathematics, topology generalizes the notion of triangulation in a natural way as follows: A triangulation of a topological space X is a simplicial complex K , homeomorphic to X , together with a homeomorphism h : K o X . Triangulation is… … Wikipedia
E₈ lattice — In mathematics, the E8 lattice is a special lattice in R8. It can be characterized as the unique positive definite, even, unimodular lattice of rank 8. The name derives from the fact that it is the root lattice of the E8 root system. The normIn… … Wikipedia
