I Fondamenti Del Calcolo

http://www.math.unifi.it/archimede/archimede/mostra_calcolo/pannelli/6.html

Extractions: Il secolo che segue la scoperta del calcolo è caratterizzato in gran parte dalla esplorazione di fenomeni fisico-matematici tramite i nuovi strumenti differenziali. Riflessioni sui fondamenti appaiono solo occasionalmente come in Eulero, che afferma che per essere rigorosi bisogna dire che gli infinitesimi non sono altro che zeri veri e propri, o in d'Alembert che nell' Encyclopedie sostiene che la "vera metafisica" del calcolo risiede nei limiti. Alla fine del secolo, nello stesso anno in cui vedono la luce le Réflexions sur la métaphysique du calcul infinitésimal di Lazare Carnot , viene pubblicato da Joseph Luis Lagrange (1736-1813) un volume che raccoglie le lezioni da lui tenute all'École Polytechnique, intitolato Théorie des fonctions analytiques (1797). Il programma, a cui Lagrange aveva già dedicato riflessioni e memorie nei decenni precedenti, è quello di costruire una teoria delle funzioni e fondare in maniera inequivocabile il calcolo infinitesimale liberandosi, secondo quanto indicato nel sottotitolo, da ogni considerazione di infinitesimi, di quantità evanescenti, di limiti e flussioni, e di ricondursi all'analisi algebrica di quantità finite. Questo viene fatto ponendo a fondamento della teoria lo sviluppo in serie di potenze e costruendo a partire da queste le funzioni "derivate", termine che viene qui introdotto.

Extractions: décédé à Sceaux le 23 mai 1857. Cauchy était ingénieur militaire et se rendit en 1810 à Cherbourg pour travailler à la flotte d'invasion de Napoléon. En 1813, il retourna à Paris et poussé par Lagrange et Laplace, il se consacra aux mathématiques. Il occupa divers postes à Paris, à la Faculté des Sciences, au Collège de France et à l'Ecole Polytechnique. En 1816, il remporta le grand prix de l'Académie des sciences. Cauchy fut un pionnier dans l'étude de l'analyse et de la théorie des groupes de substitutions (appelés maintenant permutations). Cauchy prouva en 1811 que les angles d'un polyèdre convexe sont déterminés par ses faces. En 1814, il publia un mémoire sur les intégrales définies qui devint la base de la théorie des fonctions complexes. Ses autres contributions comprennent des recherches sur la convergence et la divergence des séries infinies, les équations différentielles, les déterminants, les probabilités et la physique mathématique. De nombreux termes mathématiques portent son nom: le théorème intégral de Cauchy (en théorie des fonctions complexes), le théorème d'existence de Cauchy-Kovalewskaya (pour la résolution d'équations aux dérivées partielles), les équations de Cauchy-

Extractions: (Continuity for Real functions) One of the problems with deciding if a sequence is convergent is that you need to have a limit before you can test the definition. Bernard Bolzano was the first to spot a way round this problem by using an idea first introduced by the French mathematician Augustin Louis Cauchy (1789 to 1857). Definition A sequence is called a Cauchy sequence if the terms of the sequence eventually all become arbitrarily close to one another. That is, given N such that if m n N a m a n Remarks Note that this definition does not mention a limit and so can be checked from knowledge about the sequence. a m a m . For example, the divergent sequence of partial sums of the harmonic series ( see this earlier example ) does satisfy this property, but not the condition for a Cauchy sequence. We will see (shortly) that Cauchy sequences are the same as convergent sequences for sequences in R . However, we will see later that when we introduce the idea of convergent in a more general context Cauchy sequences and convergent sequences may be different. Cantor (1845 to 1918) used the idea of a Cauchy sequence of rationals to give a constructive definition of the Real numbers independent of the use of Dedekind Sections

Extractions: AUGUSTIN LOUIS CAUCHY Nascut: 21 august 1789 in Paris, Franta Mort: 23 mai 1875 in Sceaux (in apropiere de Paris), Franta Paris era un loc in care era greu de trait datorita evenimentelor politice din timpul Revolutiei Franceze, cand Augustin Louis Cauchy era un copil. Cand avea 4 ani tatal sau, temandu-se pentru viata sa in Paris, s-a mutat cu familia la Arcueil. Acolo viata era grea scriind: Nicidata nu avem mai mult de o jumatate de livra de paine, si cateodata nici macar atat. Pe aceasta noi o suplimentam cu o mica provizie de biscuiti tari si orez ce ne sunt distribuite Curand ei s-au intors la Paris si tatal lui Cauchy era foarte activ in educatia fiului sau. Laplace si Lagrange erau vizitatori ai familiei Cauchy si Lagrange in particular se pare ca ar fi avut un interes deosebit pentru Cauchy in domeniul matematicii. Lagrange l-a sfatuit pe tatal lui Cauchy ca fiul sau ar trebui sa obtina o buna cunoastere a limbilor straine inainte de incepe studiul profund al matematicii. In 1803 Augustin Louis s-a inscris la Scoala Centrala din Pantheon unde a petrecut 2 ani studiind limbile clasice. Din 1804 Cauchy studia matematica si a luat examenul de intrare la Scoala Politehnica in 1805. A fost examenat de Boid si a fost clasat al doilea. La Scoala Politehnica a urmat cursurile lui Lacroix, de Prony si Hachette in timp ce tutorele sau de analiza era Ampere. In 1807 a absolvit Scoala Politehnica si a intrat la scoala de inginerie Ecole de Ponts et Chaussees. A fost un student uimitor si pentru munca sa practica a fost numit la proiectul de la Canalul Ourcq unde a lucrat coordonat de Pierre Girarrd.
