44Outer automorphism group — In mathematics, the outer automorphism group of a group G is the quotient Aut(G) / Inn(G), where Aut(G) is the automorphism group of G and Inn(G) is the subgroup consisting of inner automorphisms. The outer automorphism group is usually …
45Novikov conjecture — This page concerns mathematician Sergei Novikov s topology conjecture. For astrophysicist Igor Novikov s conjecture regarding time travel, see Novikov self consistency principle. The Novikov conjecture is one of the most important unsolved… …
46Pointclass — In the mathematical field of descriptive set theory, a pointclass is a collection of sets of points, where a point is ordinarily understood to be an element of some perfect Polish space. In practice, a pointclass is usually characterized by some… …
47Nichols algebra — The Nichols algebra of a braided vector space (with the braiding often induced by a finite group) is a braided Hopf algebra which is denoted by and named after the mathematician Warren Nichols. It takes the role of quantum Borel part of a pointed …
48HASARD — Le hasard, que le calcul des probabilités a permis de maîtriser partiellement, apparaît d’abord comme un caractère fondamental de l’existence. Dans la mesure où l’incertitude enveloppe l’idée de risque, on a tenté de la réduire, dans le domaine… …
49Infinite monkey theorem — Not to be confused with Hundredth monkey effect. Given enough time, a hypothetical monkey typing at random would, as part of its output, almost surely produce all of Shakespeare s plays. In this image a chimpanzee is giving it a try. The infinite …
50Spectrum of a C*-algebra — The spectrum of a C* algebra or dual of a C* algebra A, denoted Â, is the set of unitary equivalence classes of irreducible * representations of A. A * representation π of A on a Hilbert space H is irreducible if, and only if, there is no closed… …
