In applied probability, a dynamic contagion process is a point process with stochastic intensity that generalises the Hawkes process and Cox process with...

The arithmetic rope, or knotted rope, was a widely used arithmetic tool in the Middle Ages that could be used to solve many mathematical and geometrical...

FORK-256 is a hash algorithm designed in response to security issues discovered in the earlier SHA-1 and MD5 algorithms. After substantial cryptanalysis...

In network theory, the Wiener connector is a means of maximizing efficiency in connecting specified "query vertices" in a network. Given a connected, undirected...

In mathematics, Nagao's theorem, named after Hirosi Nagao, is a result about the structure of the group of 2-by-2 invertible matrices over the ring of...

Jan Vaerman (1653–1731) was a Flemish mathematician. He worked as a school teacher first in Bruges and then, from 1693 to 1717, in Tielt. He wrote about...

Chaotic cryptology is the application of mathematical chaos theory to the practice of cryptography, the study or techniques used to privately and securely...

Wavelets are often used to analyse piece-wise smooth signals. Wavelet coefficients can efficiently represent a signal which has led to data compression...

Yi Sun (born 1975) is a Chinese management consultant. She has arranged a significant number of German companies to be sold to Chinese investors. Insolvency...

In abstract algebra, a conjugacy class sum, or simply class sum, is a function defined for each conjugacy class of a finite group G as the sum of the elements...

In mathematics, a quadratic-linear algebra is an algebra over a field with a presentation such that all relations are sums of monomials of degrees 1 or...

Copying network models are network generation models that use a copying mechanism to form a network, by repeatedly duplicating and mutating existing nodes...

Giambattista Magistrini (1777 – 1849) was an Italian mathematician. From 1804 he was professor of calculation at the University of Bologna. From 1811 he...

The Ages of Three Children puzzle (sometimes referred to as the Census-Taker Problem) is a logical puzzle in number theory which on first inspection seems...

A tape diagram is a rectangular visual model resembling a piece of tape, that is used to assist with the calculation of ratios and addition, subtraction...

In linear algebra, a completely-S matrix is a square matrix such that for every principal submatrix R there exists a positive vector u such that Ru > 0...

In statistics, Pyrrho's lemma is the result that if one adds just one extra variable as a regressor from a suitable set to a linear regression model, one...

In complex analysis (a branch of mathematical analysis), the pseudo-zero set or root neighborhood of a degree-m polynomial p(z) is the set of all complex...

Topswops (and the variants Topdrops, Bottomswops and Bottomdrops) are mathematical problems devised and analysed by the British mathematician John Conway...

In mathematics, Gottlieb polynomials are a family of discrete orthogonal polynomials given by ℓ n ( x , λ ) = e − n λ ∑ k ( 1 − e λ ) k ( n k ) ( x k )...
