41Brouwer's fixed point theorem — ▪ topology in mathematics, a theorem of algebraic topology (topology) that was stated and proved in 1912 by the Dutch mathematician L.E.J. Brouwer (Brouwer, Luitzen Egbertus Jan). Inspired by earlier work of the French mathematician Henri… …
42Greatest fixed point — In mathematics, more specifically in order theory, the greatest fixed point (gfp or GFP) of a function is the fixed point which is greater than or equal to to all other fixed points, according to some partial order. For example, the greatest… …
43Ryll-Nardzewski fixed point theorem — In functional analysis, the Ryll Nardzewski fixed point theorem states that if E is a normed vector space and K is a nonempty convex subset of E which is compact under the weak topology, then every group (or equivalently: every semigroup) of… …
44Schauder fixed point theorem — The Schauder fixed point theorem is an extension of the Brouwer fixed point theorem to topological vector spaces such as Banach spaces. It asserts that if K is a compact, convex subset of a topological vector space and T is a continuous mapping… …
45Gaussian fixed point — A Gaussian fixed point is a fixed point of the renormalization group flow which is noninteracting in the sense that it is described by a free field theory. The word Gaussian comes from the fact that the probability distribution is Gaussian at the …
46UV fixed point — A theory has a UV fixed point if its renormalization group flow runs towards a fixed point in the ultraviolet (i.e. short length scale/large energy) limit. Among other things, it means that such a theory is not an effective field theory because… …
47Banks–Zaks fixed point — In quantum chromodynamics (and also N = 1 superquantum chromodynamics) with massless flavors, if the number of flavors, Nf, is sufficiently small (that is small enough to guarantee asymptotic freedom), the theory can flow to an… …
48Banks-Zaks fixed point — In quantum chromodynamics (and also N=1 superquantum chromodynamics) with massless flavors, if the number of flavors, N f, is sufficiently small (that is small enough to guarantee asymptotic freedom), the theory can flow to an interacting… …
49Borel fixed-point theorem — In mathematics, the Borel fixed point theorem is a fixed point theorem in algebraic geometry. The result was proved by the Swiss mathematician Armand Borel in 1956.tatement of the theoremLet G be a connected, solvable algebraic group acting… …
50Fixed-Point-Arithmetik — Eine Festkommazahl ist eine Zahl, die aus einer festen Anzahl von Ziffern besteht. Die Position des Dezimalkommas ist dabei fest vorgegeben, daher der Name. Der Grundgedanke hinter Festkommazahlen ist die exakte Darstellung ohne Rundungsfehler… …
