characteristic sequence
1Characteristic sequence — In mathematics, the characteristic sequence of a given sequence s is a sequence of 1 s and 0 s which tells which elements of s are in some set. Given two sets and a sequence s = of elements of B, the characteristic sequence of s is the sequence… …
2Characteristic function (probability theory) — The characteristic function of a uniform U(–1,1) random variable. This function is real valued because it corresponds to a random variable that is symmetric around the origin; however in general case characteristic functions may be complex valued …
3Genus of a multiplicative sequence — In mathematics, the genus of a multiplicative sequence is a ring homomorphism, from the cobordism ring of smooth oriented compact manifolds to another ring, usually the ring of rational numbers.DefinitionA genus phi; assigns a number phi;( X ) to …
4Potter sequence — Not to be confused with Doege Potter syndrome or Pott s Disease. Potter sequence Classification and external resources ICD 10 Q60.6 ICD 9 …
5Light characteristic — Symbols and abbreviations for light characteristics A light characteristic is a graphic and text description of a navigational light sequence or colour displayed on a nautical chart or in a Light List with the chart symbol for a lighthouse,… …
6Algorithmically random sequence — Intuitively, an algorithmically random sequence (or random sequence) is an infinite sequence of binary digits that appears random to any algorithm. The definition applies equally well to sequences on any finite set of characters. Random sequences …
7Exact sequence — In mathematics, especially in homological algebra and other applications of abelian category theory, as well as in differential geometry and group theory, an exact sequence is a (finite or infinite) sequence of objects and morphisms between them… …
8Look-and-say sequence — The lines show the growth of the numbers of digits in the look and say sequences with starting points 23 (red), 1 (blue), 13 (violet), 312 (green). These lines (when represented in a logarithmic scale) tend to straight lines whose slopes coincide …
9Ducci sequence — A Ducci sequence is a sequence of n tuples of integers. Given an n tuple of integers (a1,a2,...,an), the next n tuple in the sequence is formed by taking the absolute differences of neighbouring integers: Another way of describing this is as… …
10Beatty sequence — A (homogeneous) Beatty sequence mathcal{B} r, is a sequence formed by successive positive integer multiples of a positive irrational number r, rounded down to the nearest integer, so that the sequence:mathcal{B} r = lfloor r floor, lfloor 2r… …
