	Augustin Louis Cauchy - Wikipedia, the free encyclopedia
		In 1833 the deposed king Charles X of France summoned Cauchy to be tutor to his grandson, the duke of Bordeaux, an appointment which enabled Cauchy to travel and thereby become acquainted with the favourable impression which his investigations had made.
		Returning to Paris in 1838, Cauchy refused a proffered chair at the Collège de France, but in 1848, the oath having been suspended, he resumed his post at the École Polytechnique, and when the oath was reinstituted after the coup d'état of 1851, Cauchy and François Arago were exempted from it.
		Cauchy had two brothers: Alexandre Laurent Cauchy (1792–1857), who became a president of a division of the court of appeal in 1847, and a judge of the court of cassation in 1849; and Eugène François Cauchy (1802–1877), a publicist who also wrote several mathematical works.

	Cauchy: The Pioneer of Analysis (Site not responding. Last check: 2007-09-06)
		Cauchy was the pioneer of rigorous analysis and bridged the gap between ancient and modern mathematics.
		Cauchy felt that in order to be an established mathematician he had to return to Paris; however, in 1813, he became ill, possibly due to depression, and was forced to return to Paris.
		Cauchy was the first to use a rigorous study of the conditions for convergence of infinite series in addition to his rigorous definition of an integral [1, p.143].

	Cauchy sequence - Wikipedia, the free encyclopedia
		In mathematical analysis, a Cauchy sequence, named after Augustin Cauchy, is a sequence whose elements become close as the sequence progresses.
		Cauchy sequences require the notion of distance so they can only be defined in a metric space.
		They are of interest because in a complete space, all such sequences converge to a limit, and one can test for "Cauchiness" without knowing the value of the limit (if it exists), in contrast to the definition of convergence.

	CATHOLIC ENCYCLOPEDIA: Augustin-Louis Cauchy
		Cauchy was a stanch adherent of the Bourbons and after the Revolution of 1830 followed Charles X into exile.
		Cauchy is best known for his achievements in the domain of mathematics, to almost every branch of which he made numerous and important contributions.
		Cauchy was also a pioneer in extending the applications of mathematics to physical science, especially to molecular mechanics, optics, and astronomy.

	Cauchy integral theorem - Wikipedia, the free encyclopedia
		In mathematics, the Cauchy integral theorem in complex analysis, named after Augustin Louis Cauchy, is an important statement about path integrals for holomorphic functions in the complex plane.
		This is significant, because one can then prove Cauchy's integral formula for these functions, and from that one can deduce that these functions are in fact infinitely often continuously differentiable.
		The Cauchy integral theorem is considerably generalized by the Cauchy integral formula and the residue theorem.

		As a probability distribution, it is known as the Cauchy distribution while among physicists it is known as the Lorentz distribution or the Breit-Wigner distribution.
		The Cauchy distribution is often cited as an example of a distribution which has no mean, variance or higher moments defined, although its mode and median are well defined and are both equal to x
		The Cauchy distribution is an infinitely divisible probability distribution.

	Cauchy
		Cauchy was the first to make a rigorous study of the conditions for convergence of infinite series in addition to his rigorous definition of an integral.
		Cauchy was elected but, after refusing to swear the oath, was not appointed and could not attend meetings or receive a salary.
		Cauchy's creative genius found broad expression not only in his work on the foundations of real and complex analysis, areas to which his name is inextricably linked, but also in many other fields.

	Biogrpahy of Cauchy
		Cauchy was the first to make a rigorous study of the conditions of convergence of infinite series in addition to his definition of an integral.

		Cauchy is best known for his work with the convergence and divergence of the infinite series and his work with the complex series.

		Having received his early education from his father Louis Francois Cauchy (1760-1848), who held several minor public appointments and counted Lagrange and Laplace among his friends, Cauchy entered cole Centrale du Pantheon in 1802, and proceeded to the cole Polytechnique in 1805, and to the cole des Pouts et Chausses in 1807.

	CAUCHY, A.L.(1789-1857)
		Cauchy was born in Paris in 1789 and recceived his early education from his father.
		Cauchy wrote extensively and profoundly in both pure and applied mathe matics, and he can probably be ranked next to Euler in volume of output.
		Cauchy's work exhibits great attention to rigor, and as such was largely reaponsible for inspiring other mathematicians to attempt the banishment of blind formal manipulation and of intuitive proofs from analysis.

		Cauchy was asked to report on the work, which studied subgroups of low index in the symmetric group, and it clearly led him to return to study permutation groups himself.

		Due to the lack of a variance for the Cauchy it is said that the Cauchy distribution is "Heavy Tailed".
		The Cauchy RV is a transform of a Uniform RV: If Y is Uniform, and represents the angle of a spinner, X would be the location on a line below the spinner that the ray from the spinner would reach.
		The Cauchy RV is also a transform of two Gaussian RVs: If X is Gaussian N(0,1) and Y is Gaussian N(0,1), then is a Cauchy RV.

		In mathematical analysis, a Cauchy sequence is a sequence whose terms become arbitrarily close to each other as the sequence progresses.
		They are of interest because, given certain conditions, all such sequences converge to a limit, and one can test for "Cauchiness" without having the value of the actual limit.

		However, he lived in very difficult times; born in the year of the French revolution, entering adulthood under Napoleon; a time when kings came and kings went, and those who were riding high on the wave on Monday might have to be fleeing for their life on Friday.
		Cauchy was a devout catholic and a strong supporter of the Jesuits; he prospered when similarly minded people were in power, languished otherwise.
		In addition Cauchy delayed publication of a paper by Abel in a journal he edited, there is even a story that he said at first he had lost it and only when the Norwegian embassy intervened did the paper miraculously reappear.
