Due to the rapidly increasing need for methods of data compression, quantization has become a flourishing field in signal and image processing and information theory. The same techniques are also used in statistics (cluster analysis), pattern recognition, and operations research (optimal location of service centers). The book gives the first mathematically rigorous account of the fundamental theory underlying these applications. The emphasis is on the asymptotics of quantization errors for absolutely continuous and special classes of singular probabilities (surface measures, self-similar measures) presenting some new results for the first time. Written for researchers and graduate students in probability theory the monograph is of potential interest to all people working in the disciplines mentioned above.

The authors present a concise but complete exposition of the mathematical theory of stable convergence and give various applications in different areas of probability theory and mathematical statistics to illustrate the usefulness of this concept. Stable convergence holds in many limit theorems of probability theory and statistics - such as the classical central limit theorem - which are usually formulated in terms of convergence in distribution. Originated by Alfred Renyi, the notion of stable convergence is stronger than the classical weak convergence of probability measures. A variety of methods is described which can be used to establish this stronger stable convergence in many limit theorems which were originally formulated only in terms of weak convergence. Naturally, these stronger limit theorems have new and stronger consequences which should not be missed by neglecting the notion of stable convergence. The presentation will be accessible to researchers and advanced students at the master's level with a solid knowledge of measure theoretic probability.

Martingale haben die Wahrscheinlichkeitstheorie derart revolutioniert, dass die Suche nach "guten" Martingalen inzwischen eine Standardmethode zur Untersuchung stochastischer Probleme ist. Das Buch fuhrt in die Theorie der reellen Martingale in diskreter Zeit ein und zeigt in Teil 2 einige ihrer Anwendungen; dazu zahlen u. a. das finanzmathematische Problem der Optionsbewertung, der Galton-Watson-Verzweigungsprozess, U-Statistiken und die unbedingte Basiseigenschaft von Martingal-Basen in Lp-Raumen. Mit zahlreichen UEbungsaufgaben zu jedem Kapitel.
