19th century[]

  • 1807 - Joseph Fourier announces his discoveries about the trigonometric decomposition of functions,
  • 1811 - Carl Friedrich Gauss discusses the meaning of integrals with complex limits and briefly examines the dependence of such integrals on the chosen path of integration,
  • 1815 - Siméon Denis Poisson carries out integrations along paths in the complex plane,
  • 1817 - Bernard Bolzano presents the intermediate value theorem — a continuous function which is negative at one point and positive at another point must be zero for at least one point in between,
  • 1822 - Augustin-Louis Cauchy presents the Cauchy integral theorem for integration around the boundary of a rectangle in the complex plane,
  • 1825 - Augustin-Louis Cauchy presents the Cauchy integral theorem for general integration paths—he assumes the function being integrated has a continuous derivative, and he introduces the theory of residues in complex analysis,
  • 1825 - André-Marie Ampère discovers Stokes' theorem,
  • 1828 - George Green introduces Green's theorem,
  • 1831 - Mikhail Vasilievich Ostrogradsky rediscovers and gives the first proof of the divergence theorem earlier described by Lagrange, Gauss and Green,
  • 1841 - Karl Weierstrass discovers but does not publish the Laurent expansion theorem,
  • 1843 - Pierre-Alphonse Laurent discovers and presents the Laurent expansion theorem,
  • 1850 - Victor Alexandre Puiseux distinguishes between poles and branch points and introduces the concept of essential singular points,
  • 1850 - George Gabriel Stokes rediscovers and proves Stokes' theorem,
  • 1861 - Karl Weierstrass starts to use the language of epsilons and deltas,
  • 1873 - Georg Frobenius presents his method for finding series solutions to linear differential equations with regular singular points,

20th century[]

  • 1908 - Josip Plemelj solves the Riemann problem about the existence of a differential equation with a given monodromic group and uses Sokhotsky - Plemelj formulae,
  • 1966 - Abraham Robinson presents non-standard analysis.
  • 1985 - Louis de Branges de Bourcia proves the Bieberbach conjecture,
