|Title:||On the Le Roux's fragmentation lemma|
|Seminar:||Symplectic Topology Seminar|
|Speaker:||Peter Spaeth, PSU|
|A. Fathi in 1980 asked whether the group of area preserving homeomorphisms of the disk that fix a neighborhood of the boundary is simple. While Fathi's question remains open, recently, F. Le Roux has shown that simplicity is equivalent to a fragmentation result in the group of compactly supported area preserving diffeomorphisms of the plane|
