121Atiyah–Hirzebruch spectral sequence — In mathematics, the Atiyah–Hirzebruch spectral sequence is a computational tool from homological algebra, designed to make possible the calculation of an extraordinary cohomology theory. For a CW complex X , or more general topological space, it… …
122Mapping cone (homological algebra) — In homological algebra, the mapping cone is a construction on a map of chain complexes inspired by the analogous construction in topology. In the theory of triangulated categories it is a kind of combined kernel and cokernel: if the chain… …
123JLO cocycle — In noncommutative geometry, the JLO cocycle is a cocycle (and thus defines a cohomology class) in entire cyclic cohomology. It is a non commutative version of the classic Chern character of the conventional differential geometry. In… …
124Induced homomorphism (algebraic topology) — In mathematics, especially in the area of topology known as algebraic topology, an induced homomorphism is a way of relating the algebraic invariants of topological spaces which are already related by a continuous function. Such homomorphism… …
125Norman Steenrod — Norman Earl Steenrod (* 22. April 1910 in Dayton in Ohio; † 14. Oktober 1971 in Princeton (New Jersey)) war ein US amerikanischer Mathematiker, der einer der Begründer der modernen algebraischen Topologie war. Inhaltsverzeichnis 1 Leben 2 Werk …

127Clifford algebra — In mathematics, Clifford algebras are a type of associative algebra. They can be thought of as one of the possible generalizations of the complex numbers and quaternions.[1][2] The theory of Clifford algebras is intimately connected with the… …
128Torus — Not to be confused with Taurus (disambiguation). This article is about the surface and mathematical concept of a torus. For other uses, see Torus (disambiguation). A torus As the distance to th …
