Query: The Topology of $SU(\infty)$ and the Group of Area-Preserving
  Diffeomorphisms of a Compact 2-manifold   Given the interest in relating the large $N$ limit of SU(N) to groups of
area-preserving diffeomorphisms, we consider the topologies of these groups and
show that both in terms of homology and homotopy, they are extremely different.
Similar conclusions are drawn for other infinite dimensional classical groups.
