We introduce the notion of a convex measure of risk, an extension of the concept of a coherent risk measure defined in Artzner et aL (1999), and we prove a corresponding extension of the representation theorem in terms of probability measures on the underlying space of scenarios. As a case...

Problems arising in Finance have become a significant source of new developments in Stochastic Analysis. We discuss some recent case studies, in particular some decomposition and representation theorems which are motivated by problems of hedging derivatives and of intertemporal consumption choice.

We study the long run behaviour of interactive Markov chains on infinite product spaces. In view of microstructure models of financial markets, the interaction has both a local and a global component. The convergence of such Markov chains is analyzed on the microscopic level and on the...

Das Buch ist eine Einführung in die Finanzmathematik. Der erste Teil des Buchs untersucht ein einfaches einperiodiges Modell, das als Grundlage für spätere Entwicklungen dient. Im zweiten Teil wird die Idee des dynamischen Hedgings von Eventualforderungen in einem mehrperiodigen Rahmen entwickelt
