The theory of complex functions is a strikingly beautiful and powerful area of mathematics. Some particularly fascinating examples are seemingly complicated integrals which are effortlessly computed after reshaping them into integrals along contours, as well as apparently difficult differential and integral equations, which can be elegantly solved using similar methods. To use them is sometimes routine but in many cases it borders on an art. The goal of the book is to introduce the reader to this beautiful area of mathematics and to teach him or her how to use these methods to solve a variety of problems ranging from computation of integrals to solving difficult integral equations. This is done with a help of numerous examples and problems with detailed solutions.

Dieses Buch behandelt die mathematischen Aspekte der modernen Bildverarbeitungsmethoden. Besonderer Schwerpunkt liegt dabei auf der Präsentation von Grundideen und Konzepten. Es werden eine Vielzahl moderner mathematischer Methoden behandelt, welche zur Lösung wichtiger, grundlegender Probleme der Bildverarbeitung eingesetzt werden. Die Grundprobleme umfassen zum Beispiel Entrauschen, Scharfzeichnen, Kantenerkennung, Inpainting. Neben elementaren Methoden wie Punktoperationen, linearen oder morphologischen Filtern stellt das Buch insbesondere neuere Methoden wie partielle Differentialgleichungen und Variationsmethoden vor.

Special functions arise in many problems of pure and applied mathematics, mathematical statistics, physics, and engineering. This book provides an up-to-date overview of numerical methods for computing special functions and discusses when to use these methods depending on the function and the range of parameters. Not only are standard and simple parameter domains considered, but methods valid for large and complex parameters are described as well. The first part of the book (basic methods) covers convergent and divergent series, Chebyshev expansions, numerical quadrature, and recurrence relations. Its focus is on the computation of special functions; however, it is suitable for general numerical courses. Pseudoalgorithms are given to help students write their own algorithms. In addition to these basic tools, the authors discuss other useful and efficient methods, such as methods for computing zeros of special functions, uniform asymptotic expansions, Padé approximations, and sequence transformations. The book also provides specific algorithms for computing several special functions (like Airy functions and parabolic cylinder functions, among others).

This book gives introductory chapters on the classical basic and standard methods for asymptotic analysis, such as Watson's lemma, Laplace's method, the saddle point and steepest descent methods, stationary phase and Darboux's method. The methods, explained in great detail, will obtain asymptotic approximations of the well-known special functions of mathematical physics and probability theory. After these introductory chapters, the methods of uniform asymptotic analysis are described in which several parameters have influence on typical phenomena: turning points and transition points, coinciding saddle and singularities. In all these examples, the special functions are indicated that describe the peculiar behavior of the integrals. The text extensively covers the classical methods with an emphasis on how to obtain expansions, and how to use the results for numerical methods, in particular for approximating special functions. In this way, we work with a computational mind: how can we use certain expansions in numerical analysis and in computer programs, how can we compute coefficients, and so on.

The subject of special functions is often presented as a collection of disparate results, which are rarely organised in a coherent way. This book answers the need for a different approach to the subject. The authors' main goals are to emphasise general unifying principles coherently and to provide clear motivation, efficient proofs, and original references for all of the principal results. The book covers standard material, but also much more, including chapters on discrete orthogonal polynomials and elliptic functions. The authors show how a very large part of the subject traces back to two equations - the hypergeometric equation and the confluent hypergeometric equation - and describe the various ways in which these equations are canonical and special. Providing ready access to theory and formulas, this book serves as an ideal graduate-level textbook as well as a convenient reference.

Die Konfluente Hypergeometrische Funktion

Mit Besonderer Berücksichtigung ihrer Anwendung

Das vorliegende Buch behandelt die unter dem Namen der konflu enten hypergeometrischen Funktion bekannte höhere transzendente Funktion, der in den physikalischen und technischen Anwendungen der Mathematik eine besonders in den letzten beiden Jahrzehnten ständig steigende Bedeutung zukommt. Es steht außer Zweifel, daß sich diese Tendenz in der Zukunft noch wesentlich verstärken wird, und so wie zunächst die Zylinderfunktionen nur von einigen Wenigen zuverlässig gehandhabt werden konnten, bis sie heute selbst schon dem rechnenden Ingenieur vertraut geworden sind, so wird auch die Theorie der all gemeineren konfluenten hypergeometrischen Funktion sehr bald einem immer größeren Kreis von Physikern geläufig sein. In diese Entwick lung soll das vorliegende Buch fördernd eingreifen. Die große praktische Bedeutung der hier behandelten Funktion bedarf schon deswegen kaum einer eingehenden Begründung, weil sie einmal eine große Zahl einfacherer spezieller Funktionen, die schon seit langem zum täglichen Werkzeug des Physikers gehören, als Sonderfälle umfaßt. Es genügt, an dieser Stelle zu erwähnen, daß dazu u. a. der Integrallogarithmus, der Integralsinus und -cosinus, das Fehlerintegral, die Fresnelschen Integrale, die Zylinderfunktionen und endlich die Funktionen des parabolischen Zylinders gehören. Es hat also derjenige, der sich die Mühe macht, die konfluente hypergeometrische Funktion eingehender zu studieren, den nicht hoch genug einzuschätzenden Vorteil, daß ihm die Theorie dieser Funktion die Eigenschaften der aus ihr ableit baren Funktionen sozusagen von einer höheren Warte aus zu über blicken gestattet.
