Tel Aviv University
Hello everyone,
The next colloquium talk will be held on Monday, 23/5/2011, 12:15,
Schreiber 006, Tel Aviv University. The speaker is
     Mariusz Lemanczyk (Copernicus University, Poland)
and the title of his talk is
     Differential equations on S^3 and topological dynamical systems
     given by cocycles
The abstract is given below. Tea and coffee at 12:00, same room.
Hope to see you there. For information about future colloquiua, see
You are all welcome to suggest colloquium speakers for the next academic
Abstract: Starting with some differential equations considered by H.
Poincare we will obtain dynamical systems which are suspensions over
cocycle extensions of some minimal systems. I will overview the theory of
cocycles over minimal rotations (focusing on paralles and differences
with measurable dynamics) and describe the current stage of knowledge
about so called Besicovitch problem (the problem of existence of discrete
orbits and potentially other minimal subsets for cylindrical
