11Uniformly hyperfinite algebra — In operator algebras, a uniformly hyperfinite, or UHF, algebra is one that is the closure, in the appropriate topology, of an increasing union of finite dimensional full matrix algebras. C* algebras A UHF C* algebra is the direct limit of an… …
12Approximately finite dimensional C*-algebra — In C* algebras, an approximately finite dimensional, or AF, C* algebra is one that is the inductive limit of a sequence of finite dimensional C* algebras. Approximate finite dimensionality was first defined and described combinatorially by… …

16Hackenbush — is a two player mathematical game which may be played on any configuration of colored line segments connected to one another by their endpoints and to the ground. More precisely, there is a ground (conventionally, but not necessarily, a… …
17Whitney covering lemma — In mathematical analysis, the Whitney covering lemma is a lemma which asserts the existence of a certain type of partition of an open set in a Euclidean space. Originally it was employed in the proof of Hassler Whitney s extension theorem. The… …
18Fraction dyadique — En mathématiques, une fraction dyadique ou rationnel dyadique est un nombre rationnel qui, lorsqu il est écrit sous forme de fraction, possède un dénominateur sous forme de puissance de deux. On peut noter l ensemble des nombres dyadiques… …
19Surreal number — In mathematics, the surreal number system is an arithmetic continuum containing the real numbers as well as infinite and infinitesimal numbers, respectively larger or smaller in absolute value than any positive real number. The surreals share… …
20Finger binary — is a system for counting and displaying binary numbers on the fingers and thumbs of one or more hands. It is possible to count from 0 to 31 (25−1) using the fingers of a single hand, or from 0 through 1023 (210−1) if both hands are used. Contents …
