Mathematics Seminars for the week of February 23, 2004
Colloquium
Thursday, 3:30, in VinH 16Professor Hillel Furstenberg
of Hebrew University, Jerusalem
will speak on
"Ergodic geometry and the role of nilpotent gorups and
nilmanifolds"
We will describe the basic ideas underlying the recent work of B.
Host and B. Kra in which they were able to establish a very general non-
conventional ergodic theorem. ``Ergodic Geometry'' enables one to isolate
``geometrically meaningful'' objects in the context of ergodic (rather than
transitive) group actions, and the rudimentary study of these leads to a
``completion'' of the acting group. The fact that this completion is
nilpotent for certain cases will play a crucial rule.
