Thomas John I'Anson Bromwich
Thomas John I'Anson Bromwich (8 February 1875 – 24 August 1929) was an English mathematician, and a Fellow of the Royal Society. Life Thomas John I'Anson Bromwich was born on 8 February 1875, in Wolverhampton, England. He was descended from Bryan I'Anson, of Ashby St Ledgers, Sheriff of London and father of the 17th century 1st Baronet Sir Bryan I'Anson of Bassetsbury. His parents emigrated to South Africa, where in 1892 he graduated from high school. He attended St John's College, Cambridge, where in 1895 he became Senior Wrangler. In 1897, he became a lecturer at St. John’s. From 1902 to 1907, he was a professor of mathematics at Queen’s College, Galway. In 1906, he was elected a Fellow of the Royal Society. In 1907, he returned to Cambridge and again became a Fellow and lecturer at St. John’s. He was a vice president of the Royal Society in 1919 and 1920. He died in Northampton on 24 August 1929, a suicide. Work Bromwich worked in both algebra and analysis. G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolverhampton
Wolverhampton () is a city, metropolitan borough and administrative centre in the West Midlands, England. The population size has increased by 5.7%, from around 249,500 in 2011 to 263,700 in 2021. People from the city are called "Wulfrunians". Historically part of Staffordshire, the city grew initially as a market town specialising in the wool trade. In the Industrial Revolution, it became a major centre for coal mining, steel production, lock making, and the manufacture of cars and motorcycles. The economy of the city is still based on engineering, including a large aerospace industry, as well as the service sector. Toponym The city is named after Wulfrun, who founded the town in 985, from the Anglo-Saxon ''Wulfrūnehēantūn'' ("Wulfrūn's high or principal enclosure or farm"). Before the Norman Conquest, the area's name appears only as variants of ''Heantune'' or ''Hamtun'', the prefix ''Wulfrun'' or similar appearing in 1070 and thereafter. Alternatively, the city ma ...

Contour Integral
In the mathematical field of complex analysis, contour integration is a method of evaluating certain integrals along paths in the complex plane. Contour integration is closely related to the calculus of residues, a method of complex analysis. One use for contour integrals is the evaluation of integrals along the real line that are not readily found by using only real variable methods. Contour integration methods include: * direct integration of a complex-valued function along a curve in the complex plane (a ''contour''); * application of the Cauchy integral formula; and * application of the residue theorem. One method can be used, or a combination of these methods, or various limiting processes, for the purpose of finding these integrals or sums. Curves in the complex plane In complex analysis a contour is a type of curve in the complex plane. In contour integration, contours provide a precise definition of the curves on which an integral may be suitably defined. A curve in t ...

People From Wolverhampton
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of pe ...

Alumni Of St John's College, Cambridge
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the ...

Bendixson's Inequality
In mathematics, Bendixson's inequality is a quantitative result in the field of matrices derived by Ivar Bendixson in 1902. The inequality puts limits on the imaginary and real parts of characteristic roots (eigenvalues) of real matrices. A special case of this inequality leads to the result that characteristic roots of a real symmetric matrix are always real. The inequality relating to the imaginary parts of characteristic roots of real matrices (Theorem I in ) is stated as: Let A = \left ( a_ \right ) be a real n \times n matrix and \alpha = \max_ \frac \left , a_ - a_ \right , . If \lambda is any characteristic root of A, then : \left , \operatorname (\lambda) \right , \le \alpha \sqrt.\, If A is symmetric then \alpha = 0 and consequently the inequality implies that \lambda must be real. The inequality relating to the real parts of characteristic roots of real matrices (Theorem II in ) is stated as: Let m and M be the smallest and largest characteristic roots of \tfrac, ...

Matrix (mathematics)
In mathematics, a matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object. For example, \begin1 & 9 & -13 \\20 & 5 & -6 \end is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a "-matrix", or a matrix of dimension . Without further specifications, matrices represent linear maps, and allow explicit computations in linear algebra. Therefore, the study of matrices is a large part of linear algebra, and most properties and operations of abstract linear algebra can be expressed in terms of matrices. For example, matrix multiplication represents composition of linear maps. Not all matrices are related to linear algebra. This is, in particular, the case in graph theory, of incidence matrices, and adjacency matrices. ''This article focuses on matrices related to linear algebra, and, unle ...

Bromwich Inequality
West Bromwich ( ) is a market town in the borough of Sandwell, West Midlands, England. Historically part of Staffordshire, it is north-west of Birmingham. West Bromwich is part of the area known as the Black Country, in terms of geography, culture and dialect. West Bromwich had a population of 77,997 in the 2011 Census. Initially a rural village, West Bromwich's growth corresponded with that of the Industrial Revolution, owing to the area's natural richness in ironstone and coal, as well as its proximity to canals and railway branches. It led to the town becoming a centre for coal mining, brick making, the iron industry and metal trades such as nails, springs and guns. The town's primary economy developed into engineering, manufacturing and the automotive industry through the early 20th century. During the Second World War, West Bromwich experienced bombing from the German Luftwaffe. It also suffered heavily during recessions in the mid 1970s, early 1980s and late 2000s. ...

Quadratic Form
In mathematics, a quadratic form is a polynomial with terms all of degree two ("form" is another name for a homogeneous polynomial). For example, :4x^2 + 2xy - 3y^2 is a quadratic form in the variables and . The coefficients usually belong to a fixed field , such as the real or complex numbers, and one speaks of a quadratic form over . If K=\mathbb R, and the quadratic form takes zero only when all variables are simultaneously zero, then it is a definite quadratic form, otherwise it is an isotropic quadratic form. Quadratic forms occupy a central place in various branches of mathematics, including number theory, linear algebra, group theory (orthogonal group), differential geometry (Riemannian metric, second fundamental form), differential topology ( intersection forms of four-manifolds), and Lie theory (the Killing form). Quadratic forms are not to be confused with a quadratic equation, which has only one variable and includes terms of degree two or less. A quadratic form is ...
