Documentary film "Wolfgang Doeblin: A Mathematician Rediscovered".
A demonsration was presented by the aithors of the film, Agnes Handwerk and Harrie Willems, and commented by the specialists B.Lifshits and A.Borodin.
Wolfgang Doeblin, one of the great probabilists of the 20th century, was already widely known in the 1950s for his fundamental contributions to the theory of Markov chains. His coupling method became a key tool in later developments at the interface of probability and statistical mechanics. But the full measure of his mathematical stature became apparent only in 2000 when the sealed envelope containing his construction of diffusion processes in terms of a time change of Brownian motion was finally opened, 60 years after it was sent to the Academy of Sciences in Paris. The film of Agnes Handwerk and Harrie Willems documents scientific and human aspects of this amazing discovery and throws new light on the startling circumstances of his death at the age of 25.

I. H. Sloan (Sydney). Lifting the curse of dimensionality: numerical integration in high dimensions. I.Sloan
Richard Bellmann coined the phrase "the curse of dimensionality" to describe the extraordinarily rapid increase in the difficulty of most problems as the number of variables increases. A typical problem is numerical multiple integration, where the cost of any integration formula of product type obviously rises exponentially with the number of variables. Nevertheless, problems with hundreds or even thousands of variables do arise, and are now being tackled successfully. In this talk I will describe recent strategies, mathematical settings, and constructions with which suitable integration problems (from mathematical finance, for example) are being successfully handled.
