111Möbius function — This article is about the number theoretic Möbius function. For the combinatorial Möbius function, see incidence algebra. For the rational functions defined on the complex numbers, see Möbius transformation. The classical Möbius function μ(n) is… …
112Glossary of ring theory — Ring theory is the branch of mathematics in which rings are studied: that is, structures supporting both an addition and a multiplication operation. This is a glossary of some terms of the subject. Contents 1 Definition of a ring 2 Types of… …
113Character (mathematics) — In mathematics, a character is (most commonly) a special kind of function from a group to a field (such as the complex numbers). There are at least two distinct, but overlapping meanings. Other uses of the word character are almost always… …

115Persistence of a number — In mathematics, the persistence of a number is a term used to describe the number of times one must apply a given operation to an integer before reaching a fixed point, i.e. until further application does not change the number any more. Usually,… …
116Bell series — In mathematics, the Bell series is a formal power series used to study properties of arithmetical functions. Bell series were introduced and developed by Eric Temple Bell.Given an arithmetic function f and a prime p, define the formal power… …
117Construction of t-norms — In mathematics, t norms are a special kind of binary operations on the real unit interval [0, 1]. Various constructions of t norms, either by explicit definition or by transformation from previously known functions, provide a plenitude of… …
118Querprodukt — Das Querprodukt einer natürlichen Zahl ist – analog zur Quersumme – das Produkt ihrer Ziffernwerte. Ebenso wie die Quersumme ist auch das Querprodukt zahlensystemabhängig. Das dezimale Querprodukt von 5496 ist beispielsweise 5·4·9·6 = 1080. Im… …
