   Oleg Lepski (University of Provence, France)
and the title of his talk is

The abstract is given below. Tea and coffee at 12:00, same room.
Hope to see you there. For information about future colloqiua, see
You are all welcome to suggest colloquium speakers for this semester.
Abstract: The main objective of the talk is to look from a unique point of
view at some phenomena arising in different areas of probability theory and
mathematical statistics. In particular, we will try to understand what is
common between classical probabilistic results, such as the law of iterated
logarithm for example, and a well-known problem in adaptive estimation
called price to pay for adaptation. Why do there exist two different kinds
of this price? It turned out that all of these and many others problems can
be reduced to finding upper functions for a collection of positives random
