a fixed point
31Gaussian 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 …
32UV 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… …
33fixed-point — adjective Date: 1948 involving or being a mathematical notation (as in a decimal system) in which the point separating whole numbers and fractions is fixed compare floating point …
34fixed-point — noun Being or using an internal number representation with a fixed number of decimal places (as opposed to floating point) …
35fixed point — /fɪkst ˈpɔɪnt/ (say fikst poynt) noun any accurately reproducible equilibrium temperature, as ice point, steam point, sulphur point and the triple point …
36fixed point — noun 1》 Physics a well defined reproducible temperature which can be used as a reference point, e.g. one defined by a change of phase. 2》 [as modifier] Computing denoting a mode of representing a number by a single sequence of digits whose values …
37Kakutani fixed point theorem — In mathematical analysis, the Kakutani fixed point theorem is a fixed point theorem for set valued functions. It provides sufficient conditions for a set valued function defined on a convex, compact subset of a Euclidean space to have a fixed… …
38Brouwer fixed point theorem — In mathematics, the Brouwer fixed point theorem is an important fixed point theorem that applies to finite dimensional spaces and which forms the basis for several general fixed point theorems. It is named after Dutch mathematician L. E. J.… …
39Banach fixed-point theorem — In mathematics, the Banach fixed point theorem (also known as the contraction mapping theorem or contraction mapping principle) is an important tool in the theory of metric spaces; it guarantees the existence and uniqueness of fixed points of… …
