In control system theory, the Routh–Hurwitz stability criterion is a mathematical test that is a necessary and sufficient condition for the stability of a linear time invariant (LTI) control system.
 The Routh test is an efficient recursive algorithm that English mathematician Edward John Routh proposed in 1876 to determine whether all the roots of the characteristic polynomial of a linear system have negative real parts.
 German mathematician Adolf Hurwitz independently proposed in 1895 to arrange the coefficients of the polynomial into a square matrix, called the Hurwitz matrix, and showed that the polynomial is stable if and only if the sequence of determinants of its principal submatrices are all positive.
 The two procedures are equivalent, with the Routh test providing a more efficient way to compute the Hurwitz determinants than computing them directly.
 A polynomial satisfying the Routh–Hurwitz criterion is called a Hurwitz polynomial.
In mathematics, specifically in number theory, a Cunningham number is a certain kind of integer named after English mathematician A. J. C. Cunningham.
Lewis Fry Richardson, FRS (11 October 1881 – 30 September 1953) was an English mathematician, physicist, meteorologist, psychologist and pacifist who pioneered modern mathematical techniques of weather forecasting, and the application of similar techniques to studying the causes of wars and how to prevent them.
 He is also noted for his pioneering work concerning fractals and a method for solving a system of linear equations known as modified Richardson iteration.
The Bulk Richardson Number (BRN) is an approximation of the Gradient Richardson number.
 The BRN is a dimensionless ratio in meteorology related to the consumption of turbulence divided by the shear production (the generation of turbulence kinetic energy caused by wind shear) of turbulence.
 It is used to show dynamic stability and the formation of turbulence.
Sir Henry Peter Francis Swinnerton-Dyer, 16th Baronet {'1': ", '2': ", '3': ", '4': "} (born 2 August 1927), commonly known as Peter Swinnerton-Dyer, is an English mathematician specialising in number theory at University of Cambridge.
 As a mathematician he is best known for his part in the Birch and Swinnerton-Dyer conjecture relating algebraic properties of elliptic curves to special values of L-functions, which was developed with Bryan Birch during the first half of the 1960s with the help of machine computation, and for his work on the Titan operating system.
Reuben Burrow (30 December 1747 – 7 June 1792) was an English mathematician, surveyor and orientalist.
 Initially a teacher, he was appointed assistant to Sir Nevil Maskelyne, then astronomer-royal, at the Royal Greenwich Observatory and was involved in the Schiehallion experiment.
 He later conducted research in India, teaching himself Sanskrit and becoming one of the first members of the Asiatic Society.
 He was the first to measure the length of a degree of an arc of longitude along the Tropic of Cancer.
 His other major achievements included a study of Indian mathematics although he earned a reputation for being coarse alongside the upper-class upbringing of the leading figures in science of the period.
 He earned a reputation as ""an able mathematician but a most vulgar and scurrilous dog.""
George Anderson (fl.
 1736 – 1740), was an English mathematician, about whom nothing is known beyond what is contained in eight letters addressed by him to the celebrated mathematician, William Jones (father of Sir W. Jones, the Orientalist), which were printed from the Macclesfield papers in 1841.
 They give proof of singular ability in treating the most advanced mathematical problems of the time, and by many indications show the writer (contrary to an editorial surmise) to have occupied a respectable position in life.
 The first three are dated from Twickenham.
 August to October 1736; the last was written 27 September 1740, at Leyden, where the writer had just entered upon a ‘train of studies and exercises’ at the university.
 He expressed in 1739 a strong desire to be admitted to the Royal Society, but his name does not appear upon the list of its members.
The Richardson number (Ri) is named after Lewis Fry Richardson (1881 – 1953).
 It is the dimensionless number that expresses the ratio of the buoyancy term to the flow shear term:
In number theory, Waring's prime number conjecture is a theorem related to Vinogradov's theorem, named after the English mathematician Edward Waring.
 It states that every odd number exceeding 3 is either a prime number or the sum of three prime numbers.
 It follows from the generalized Riemann hypothesis and (trivially) from Goldbach's weak conjecture.
A Wilson prime, named after English mathematician John Wilson, is a prime number "p" such that "p" divides ("p" − 1)!
 + 1, where "!"
 denotes the factorial function; compare this with Wilson's theorem, which states that every prime "p" divides ("p" − 1)!
 + 1.
