Classic three-volume study. Volume 1 covers applications to geometry, expansion in series, definite integrals, and derivatives and differentials. Volume 2 explores functions of a complex variable and differential equations. Volume 3 surveys variations of solutions and partial differential equations of the second order and integral equations and calculus of variations.

Leçons sur l'intégration des équations aux dérivées partielles du 1er faites à la Faculté des sciences de Paris... / par É. Goursat, ... et rédigées par C. Bourlet, ...Date de l'édition 1891Le présent ouvrage s'inscrit dans une politique de conservation patrimoniale des ouvrages de la littérature Française mise en place avec la BNF.HACHETTE LIVRE et la BNF proposent ainsi un catalogue de titres indisponibles, la BNF ayant numérisé ces oeuvres et HACHETTE LIVRE les imprimant à la demande.Certains de ces ouvrages reflètent des courants de pensée caractéristiques de leur époque, mais qui seraient aujourd'hui jugés condamnables.Ils n'en appartiennent pas moins à l'histoire des idées en France et sont susceptibles de présenter un intérêt scientifique ou historique.Le sens de notre démarche éditoriale consiste ainsi à permettre l'accès à ces oeuvres sans pour autant que nous en cautionnions en aucune façon le contenu.Pour plus d'informations, rendez-vous sur www.hachettebnf.fr

Excerpt from Leçons sur l'Intégration des Équations aux Dérivées Partielles du Second Ordre A Deux Variables IndépendantesM. Bourlet et mon éditeur, M Hermann. M'ont continué pour ce second volume le concours qu iis m'avaient prêté pour le pre mier. M. E. Cosserat, qui a pris une part active à la correction des épreuves, m'a soumis sur plusieurs points des remarques «tout j'ai profité pour ma rédaction. M. Léonce Laugel, bien connu du public mathématique par les nombreuses traductions qu'il a déjà publiées, a bien voulu traduire pour moi plusieurs mémoires importants. Je leur adresse à tous mes all'ectueux remerciements.

Excerpt from Leçons sur le Problème de PfaffEnfin, dans les trois derniers Chapitres, j'expose quelques uns des progrès les plus récents acquis à la Science, relatifs aux systèmes de Pfaff. Les plus importants de ces progrès sont dus à M. Cartan, dont on trouvera le nom presque à chaque page de ces trois Chapitres. Je souhaite que cet exposé rapide puisse engager les jeunes mathématiciens à étudier plus à fond ces élégantes méthodes, dont l'auteur a déjà fait de si belles applications.

Excerpt from Leçons sur l'Intégration des Équations aux Dérivées Partielles du Second Ordre à Deux Variables IndépendantesDans le dernier chapitre, j'étends la. Notion de caractéristiques à des équations de forme quelconque, et je démontre en toute rigueur que tous les éléments d'une caractéristique appar tiennent, cn général, à une infinité d'intégrales, dépendant d'une infinité de constantes arbitraires. J'insiste assez longuement sur une distinction essentielle entre les deux espèces de caractéris tiques, da premier ordre et du second ordre, distinction qu'am père avait déjà faite, en partant de considérations a priori sur la forme des intégrales. A la théorie des caractéristiques du premier ordre se rattache laiecherche des intégrales intermédiaires. L'étude du cas où les équations qui déterminent ces intégrales intermédiaires forment un système en involution m'a conduit à une classe nouvelle et assez étendue d'équations integrables, pour lesquelles les deux systèmes de caractéristiques sont confondus.

Excerpt from Differental EquationsThe present volume consists of the second half of the second volume of the French edition of Goursat's Cours d'analyse Mathématique. As was stated in the preface to the first half of this volume, it seemed best, for purposes of American schools, to issue these two parts separately, and this was done 'with the approval of Professor Goursat.

Edouard Goursat's famous three-volume Course in Mathematical Analysis remains a true classic of modern mathematics - fundamental material treated with brilliant clarity and thoroughness. As an advanced calculus text for the student with one year of calculus, it offers an exceptionally wide range of subject matter within the topics of analysis and applied mathematics.The second part of Volume II is devoted to differential equations. Partial equations of first and higher orders, existence theorems. Cauchy-Lipschitz method, linear and non-linear differential equations (including the study of such partial equations as D'Alembert's method, Euler's. and Laplace's equations and of exceptional initial values), and much more.

Excerpt from Functions of a Complex Being Part I of Volume IIAfter the cordial reception given to the translation of Goursat's first volume, the continuation was assured. That it has been delayed so long was due, in the first instance, to our desire to await the appearance of the second edition of the second volume in French. The advantage in doing so will be obvious to those who have observed the radical changes made in the second (french) edition of the second volume. Volume I was not altered so radi cally, so that the present English translation of that volume may be used conveniently as a companion to this; but references are given here to both editions of the first volume, to avoid any possible difficulty in this connection.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
