- Augustin-Louis Cauchy presents the Cauchy integral theoremComplex analysis Theorems The Cauchy integral theorem in complex analysis is an important statement about path integrals for holomorphic functions in the complex plane. Essentially, it says that if two different paths connect the same two points, and a fu for general integration paths -- he assumes the function being integrated has a continuous derivative
- Augustin-Louis Cauchy introduces the theory of residues in complex analysisComplex analysis is the branch of mathematics investigating holomorphic functions, i. functions which are defined in some region of the complex plane, take complex values, and are differentiable as complex functions. Complex differentiability has much str
- Johann Peter Gustav Lejeune DirichletJohann Peter Gustav Lejeune Dirichlet ( February 13, 1805 May 5, 1859) was a German mathematician credited with the modern "formal" definition of a function. His family hailed from the town of Richelet in Belgium, from which his surname "Lejeune Dirichlet and Adrien-Marie LegendreAdrien-Marie Legendre ( September 18 1752 January 10 1833) was a French mathematician. He made important contributions to statistics, number theory, abstract algebra and mathematical analysis. Most of his work was brought to perfection by others: his work prove Fermat's last theoremFermat's last theorem (sometimes abbreviated as FLT and also called Fermat's great theorem is one of the most famous theorems in the history of mathematics. It states that: :There are no positive natural numbers a b and c such that where n is a natural nu for n = 5
- André-Marie AmpèreAndre-Marie Ampere ( January 22 1775 June 10 1836), was a French physicist who is generally credited as one of the main discoverers of electromagnetism. The ampere unit of measurement of electric current is named after him. He was born at Poleymieux-au-Mo discovers Stokes' theoremStokes' theorem in differential geometry is a statement about the integration of differential forms which generalizes several theorems from vector calculus. It is named after Sir George Gabriel Stokes ( 1819- 1903). Let M be an oriented piecewise smooth m

- Georges CuvierBaron Georges Leopold Chretien Frederic Dagobert Cuvier ( August 23 1769 May 13, 1832) was a French naturalist, He was born at Montbeliard (then Mompelgard in Wurttemberg) under the name of Georg Kuefer, and was the son of a retired officer on half-pay be proposes his catastrophe theory as the cause of extinctions of large groups of animals
