| Abstract: |

| 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 |
