Augustin-Louis Cauchy         

Baron Augustin-Louis Cauchy (, koh-SHEE; French: [oɡystɛ̃ lwi koʃi]; 21 August 1789 – 23 May 1857) was a French mathematician, engineer, and physicist who made pioneering contributions to several branches of mathematics, including mathematical analysis and continuum mechanics. He was one of the first to state and rigorously prove theorems of calculus, rejecting the heuristic principle of the generality of algebra of earlier authors. He almost singlehandedly founded complex analysis and the study of permutation groups in abstract algebra.

A profound mathematician, Cauchy had a great influence over his contemporaries and successors; Hans Freudenthal stated: "More concepts and theorems have been named for Cauchy than for any other mathematician (in elasticity alone there are sixteen concepts and theorems named for Cauchy)." Cauchy was a prolific writer; he wrote approximately eight hundred research articles and five complete textbooks on a variety of topics in the fields of mathematics and mathematical physics.

  • Fitted cumulative Cauchy distribution to maximum one-day rainfalls using [[CumFreq]], see also [[distribution fitting]]<ref name=cumfreq/>
  • Estimating the mean and standard deviation through samples from a Cauchy distribution (bottom) does not converge with more samples, as in the [[normal distribution]] (top). There can be arbitrarily large jumps in the estimates, as seen in the graphs on the bottom. (Click to expand)

THEOREM
Cauchy-Hadamard Theorem; Cauchy-hadamard theorem; Cauchy-Hadamard theorem
In mathematics, the Cauchy–Hadamard theorem is a result in complex analysis named after the French mathematicians Augustin Louis Cauchy and Jacques Hadamard, describing the radius of convergence of a power series. It was published in 1821 by Cauchy,.

  • A visual depiction of a vector X in a domain being multiplied by a complex number z, then mapped by f, versus being mapped by f then being multiplied by z afterwards. If both of these result in the point ending up in the same place for all X and z, then f satisfies the Cauchy–Riemann condition
  • stationary point]] of the potential flow, with six streamlines meeting, and six equipotentials also meeting and bisecting the angles formed by the streamlines.

In the field of complex analysis in mathematics, the Cauchy–Riemann equations, named after Augustin Cauchy and Bernhard Riemann, consist of a system of two partial differential equations which, together with certain continuity and differentiability criteria, form a necessary and sufficient condition for a complex function to be holomorphic (complex differentiable). This system of equations first appeared in the work of Jean le Rond d'Alembert.
Cauchy sequence         
SEQUENCE WHOSE ELEMENTS BECOME ARBITRARILY CLOSE TO EACH OTHER
Cauchy sequences; Regular Cauchy sequence; Cauchy Sequences; Cauchy Sequence
<mathematics> A sequence of elements from some vector space that converge and stay arbitrarily close to each other (using the norm definied for the space). (2000-03-10)
Cauchy sequence         
SEQUENCE WHOSE ELEMENTS BECOME ARBITRARILY CLOSE TO EACH OTHER
Cauchy sequences; Regular Cauchy sequence; Cauchy Sequences; Cauchy Sequence
In mathematics, a Cauchy sequence (; ), named after Augustin-Louis Cauchy, is a sequence whose elements become arbitrarily close to each other as the sequence progresses. More precisely, given any small positive distance, all but a finite number of elements of the sequence are less than that given distance from each other.
Cauchy surface         
PLANE IN SPACE-TIME WHICH IS LIKE AN INSTANT OF TIME; SUBSET OF SPACE-TIME WHICH IS INTERSECTED BY EVERY INEXTENSIBLE, NON-SPACELIKE (I.E. CAUSAL) CURVE EXACTLY ONCE
Cauchy Surface; Inner horizon
In the mathematical field of Lorentzian geometry, a Cauchy surface is a certain kind of submanifold of a Lorentzian manifold. In the application of Lorentzian geometry to the physics of general relativity, a Cauchy surface is usually interpreted as defining an "instant of time"; in the mathematics of general relativity, Cauchy surfaces are important in the formulation of the Einstein equations as an evolutionary problem.
Cauchy problem         
MATHEMATICAL PROBLEM
Cauchy problems; Cauchy's problem
A Cauchy problem in mathematics asks for the solution of a partial differential equation that satisfies certain conditions that are given on a hypersurface in the domain.Jacques Hadamard (1923), Lectures on Cauchy's Problem in Linear Partial Differential Equations, Dover Phoenix editions A Cauchy problem can be an initial value problem or a boundary value problem (for this case see also Cauchy boundary condition).
