Eugène Rouché
Eugène Rouché (18 August 1832 – 19 August 1910) was a French mathematician. Career He was an alumnus of the École Polytechnique, which he entered in 1852. He went on to become professor of mathematics at the Charlemagne lyceum then at the École Centrale, and admissions examiner at his alma mater. He is best known for Rouché's theorem in complex analysis, which he published in his alma mater's institutional journal in 1862, and for the Rouché–Capelli theorem in linear algebra. His son, Jacques, was a noted patron of the arts who managed the Paris Opera for thirty years (1914–1944).

19th-century French Mathematicians
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ...

People From Gard
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 ...

1910 Deaths
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Paris Opera
The Paris Opera (, ) is the primary opera and ballet company of France. It was founded in 1669 by Louis XIV as the , and shortly thereafter was placed under the leadership of Jean-Baptiste Lully and officially renamed the , but continued to be known more simply as the . Classical ballet as it is known today arose within the Paris Opera as the Paris Opera Ballet and has remained an integral and important part of the company. Currently called the , it mainly produces operas at its modern 2,723-seat theatre Opéra Bastille which opened in 1989, and ballets and some classical operas at the older 1,979-seat Palais Garnier which opened in 1875. Small scale and contemporary works are also staged in the 500-seat Amphitheatre under the Opéra Bastille. The company's annual budget is in the order of 200 million euros, of which €100M come from the French state and €70M from box office receipts. With this money, the company runs the two houses and supports a large permanent staff, ...

Linear Algebra
Linear algebra is the branch of mathematics concerning linear equations such as: :a_1x_1+\cdots +a_nx_n=b, linear maps such as: :(x_1, \ldots, x_n) \mapsto a_1x_1+\cdots +a_nx_n, and their representations in vector spaces and through matrices. Linear algebra is central to almost all areas of mathematics. For instance, linear algebra is fundamental in modern presentations of geometry, including for defining basic objects such as lines, planes and rotations. Also, functional analysis, a branch of mathematical analysis, may be viewed as the application of linear algebra to spaces of functions. Linear algebra is also used in most sciences and fields of engineering, because it allows modeling many natural phenomena, and computing efficiently with such models. For nonlinear systems, which cannot be modeled with linear algebra, it is often used for dealing with first-order approximations, using the fact that the differential of a multivariate function at a point is the linear ma ...

Lunel, Hérault
Lunel (; Provençal: ''Lunèl'') is a commune in the Hérault department in southern France. According to legend, Lunel was founded by Jews from Jericho in the first century. It had a Jewish population by the first millennium, and an ancient synagogue is located there. Lunel is located east of Montpellier and southwest of Nîmes (Gard). Lunel station has rail connections to Narbonne, Montpellier, Nîmes and Avignon. History The ancient Roman site of Ambrussum is located nearby. The troubadour Folquet de Lunel was from Lunel. Lunel was a centre of Jewish learning. It is thought that the family of Rashi (1040–1105), the great Rabbi and commentator, originated in Lunel. Other scholars include Jonathan of Lunel, Meshullam ben Jacob of Lunel, his son Aaron ben Meshullam ben Jacob of Lunel, Abraham ben David who taught in Lunel before moving to Posquières, and Asher ben Meshullam of Lunel. Lunel was the birthplace of Louis Feuillade (1873–1925), film director fro ...

Complex Analysis
Complex analysis, traditionally known as the theory of functions of a complex variable, is the branch of mathematical analysis that investigates Function (mathematics), functions of complex numbers. It is helpful in many branches of mathematics, including algebraic geometry, number theory, analytic combinatorics, applied mathematics; as well as in physics, including the branches of hydrodynamics, thermodynamics, and particularly quantum mechanics. By extension, use of complex analysis also has applications in engineering fields such as nuclear engineering, nuclear, aerospace engineering, aerospace, mechanical engineering, mechanical and electrical engineering. As a differentiable function of a complex variable is equal to its Taylor series (that is, it is Analyticity of holomorphic functions, analytic), complex analysis is particularly concerned with analytic functions of a complex variable (that is, holomorphic functions). History Complex analysis is one of the classical ...
