Main sequence — A Hertzsprung Russell diagram plots the actual brightness (or absolute magnitude) of a star against its color index (represented as B V). The main sequence is visible as a prominent diagonal band that runs from the upper left to the lower right.… … Wikipedia
Schnirelmann density — In additive number theory, the Schnirelmann density of a sequence of numbers is a way to measure how dense the sequence is. It is named after Russian mathematician L.G. Schnirelmann, who was the first to study it. Contents 1 Definition 2… … Wikipedia
Spectral density — In statistical signal processing and physics, the spectral density, power spectral density (PSD), or energy spectral density (ESD), is a positive real function of a frequency variable associated with a stationary stochastic process, or a… … Wikipedia
Sylvester's sequence — In number theory, Sylvester s sequence is a sequence of integers in which each member of the sequence is the product of the previous members, plus one. The first few terms of the sequence are::2, 3, 7, 43, 1807, 3263443, 10650056950807,… … Wikipedia
Natural density — In number theory, asymptotic density (or natural density or arithmetic density) is one of the possibilities to measure how large a subset of the set of natural numbers is. Intuitively, we think that there are more positive integers than perfect… … Wikipedia
Choice sequence — In intuitionistic mathematics, a choice sequence is a constructive formulation of a sequence. Since the Intuitionistic school of mathematics, as formulated by L. E. J. Brouwer, rejects the idea of a completed infinity, in order to use a sequence… … Wikipedia
Kolakoski sequence — In mathematics, the Kolakoski sequence is an infinite list that begins with 1,2,2,1,1,2,1,2,2,1,2,2,1,1,2,1,1,2,2,1,2,1,1,2,1,2,2,1,1,... This is an example of a self generating sequence, as indicated here:(1) write 1; read it as the number of 1… … Wikipedia
Maximum likelihood sequence estimation — (MLSE) is a mathematical algorithm to extract useful data out of a noisy data stream. Contents 1 Theory 2 Background 3 References 4 Further reading … Wikipedia

Dirichlet density — This article is not about the Dirichlet distribution of probability theory. In mathematics, the Dirichlet density (or analytic density) of a set of primes, named after Johann Gustav Dirichlet, is a measure of the size of the set that is easier to … Wikipedia
Recurrence period density entropy — (RPDE) is a method, in the fields of dynamical systems, stochastic processes, and time series analysis, for determining the periodicity, or repetitiveness of a signal. Overview Recurrence period density entropy is useful for characterising the… … Wikipedia
