|Title:||Special representations of group actions and low complexity tilings of groups|
|Seminar:||Dynamical systems seminar|
|Speaker:||Ayse Sahin, DePaul University|
|Generalizing a result of Alpern, Rudolph showed that the orbits of any measurable, measure preserving R^d action can be measurably tiled by 2^d rectangles and asked if this number of tiles is optimal. In joint work with B. Kra and A. Quas, we show that d+1 tiles suffice. Furthermore, for flows with completely positive entropy, this bound is optimal.|
