  2. Algebraic topology - Wikipedia

    en.wikipedia.org/wiki/Algebraic_topology

    A torus, one of the most frequently studied objects in algebraic topology. Algebraic topology is a branch of mathematics that uses tools from abstract algebra to study topological spaces. The basic goal is to find algebraic invariants that classify topological spaces up to homeomorphism, though usually most classify up to homotopy equivalence.

  3. Homotopy group - Wikipedia

    en.wikipedia.org/wiki/Homotopy_group

    In mathematics, homotopy groups are used in algebraic topology to classify topological spaces. The first and simplest homotopy group is the fundamental group , denoted π 1 ( X ) , {\displaystyle \pi _{1}(X),} which records information about loops in a space .

    en.wikipedia.org/wiki/Homotopy_theory

    A CW complex is a space that has a filtration whose union is and such that . is a discrete space, called the set of 0-cells (vertices) in .; Each is obtained by attaching several n-disks, n-cells, to via maps ; i.e., the boundary of an n-disk is identified with the image of in .

    en.wikipedia.org/wiki/Homotopy_groups_of_spheres

    Stable algebraic topology flourished between 1945 and 1966 with many important results. [19] In 1953 George W. Whitehead showed that there is a metastable range for the homotopy groups of spheres. Jean-Pierre Serre used spectral sequences to show that most of these groups are finite, the exceptions being π n ( S n ) and π 4 n −1 ( S 2 n ) .

  7. Hurewicz theorem - Wikipedia

    en.wikipedia.org/wiki/Hurewicz_theorem

    In mathematics, the Hurewicz theorem is a basic result of algebraic topology, connecting homotopy theory with homology theory via a map known as the Hurewicz homomorphism. The theorem is named after Witold Hurewicz , and generalizes earlier results of Henri Poincaré .

  8. Fundamental group - Wikipedia

    en.wikipedia.org/wiki/Fundamental_group

    In the mathematical field of algebraic topology, the fundamental group of a topological space is the group of the equivalence classes under homotopy of the loops contained in the space.

  9. Topological algebra - Wikipedia

    en.wikipedia.org/wiki/Topological_algebra

    A topological algebra over a topological field is a topological vector space together with a bilinear multiplication ⋅ : A × A → A {\displaystyle \cdot :A\times A\to A} , ( a , b ) ↦ a ⋅ b {\displaystyle (a,b)\mapsto a\cdot b}
