Branching processes are stochastic processes which represent the reproduction of particles, such as individuals within a population, and thereby model demographic stochasticity. In branching processes in random environment (BPREs), additional environmental stochasticity is incorporated, meaning that the conditions of reproduction may vary in a random fashion from one generation to the next.

This book offers an introduction to the basics of BPREs and then presents the cases of critical and subcritical processes in detail, the latter dividing into weakly, intermediate, and strongly...

The Lebesgue integral is an essential tool in the fields of analysis and stochastics and for this reason, in many areas where mathematics is applied. This textbook is a concise, lecture-tested introduction to measure and integration theory. It addresses the important topics of this theory and presents additional results which establish connections to other areas of mathematics. The arrangement of the material should allow the adoption of this textbook in differently composed Bachelor programmes.

In der modernen Stochastik werden Wahrscheinlichkeiten im Zusammenhang mit Zufallsvariablen gedacht. Damit macht dieses Lehrbuch Ernst, schon die Welt uniform verteilter Zufallsgroen wird dann farbig. Das Konzept der Zufallsgroen pragt den Aufbau des Buches. Es enthalt neue Beispiele und dringt auf knappem Raum weit in das Rechnen mit Zufallsvariablen vor, ohne Techniken aus der Ma- und Integrationstheorie zu bemuhen. Die wichtigsten diskreten und kontinuierlichen Verteilungen werden erklart, und der Umgang mit Erwartungswert, Varianz und bedingten Verteilungen wird vermittelt. Der Text...
