A. Ostrowski - Böcker

Der vorliegende zweite Band meiner Aufgabensammlung entspricht in der Auswahl des Stoffes dem Inhalt des zweiten Bandes meiner "Vorlesungen über Differential- und Integralrechnung". Er enthält neben den Ergänzungen zur Infinitesimalrechnung einer Variablen grundlegenden Stoff aus der Infinitesimalrechnung mit mehreren Vari­ ablen nebst Anwendungen auf numerische Rechenmethoden, sowie auf die Differentialgeometrie. Das Buch kann natürlich auch ohne gleich­ zeitige Benutzung meines Lehrbuches verwendet werden, da auch in diesem Band in jedem Abschnitt der in Frage kommende Hintergrund an Begriffen, Formeln und Sätzen zusammengestellt ist, von dem aus die Aufgaben angepackt werden können. Wie im ersten Band, sind die Lösungen der Aufgaben zumeist in zwei Schritten angegeben, zuerst in den "Hinweisen" und sodann in den "Lösungen" . Aus praktischen Gründen ist dieser Band in zwei getrennte und einzeln erhältliche Teilbände aufgeteilt worden, von denen der erste (II A) Aufgaben und Hinweise und der zweite (II B) Lösungen enthält. Der Verlag hat wie immer den zahlreichen Wünschen des Autors mit freundlicher Geduld und Ausdauer entsprochen.

This publication was made possible through a bequest from my beloved late wife. United together in this present collection are those works by the author which have not previously appeared in book form. The following are excepted: Vorlesungen uber Differential und Integralrechnung (Lectures on Differential and Integral Calculus) Vols 1-3, Birkhauser Verlag, Basel (1965-1968); Aufgabensammlung zur Infinitesimalrechnung (Exercises in Infinitesimal Calculus) Vols 1, 2a, 2b, and 3, Birkhauser Verlag, Basel (1967-1977); two issues from Memorial des Sciences on Conformal Mapping (written together with C. Gattegno), Gauthier-Villars, Paris (1949); Solution of Equations in Euc1idean and Banach Spaces, Academic Press, New York (1973); and Stu- dien uber den Schottkyschen Satz (Studies on Schottky's Theorem), Wepf & Co., Basel (1931). Where corrections have had to be implemented in the text of certain papers, references to these are made at the conc1usion of each paper. In the few instances where this system does not, for technical reasons, seem appropriate, an asterisk in the page margin indicates wherever a correction is necessary and this is then given at the end of the paper.(There is one exception: the correc- tions to the paper on page 561 are presented on page 722. The works are published in 6 volumes and are arranged under 16 topic headings. Within each heading, the papers are ordered chronologically according to the date of original publication.
