DESCRIPTION:An approximate unitary representation of a group G is a map f 
 : G → U (n)\nwhere n is a positive integer and f (g)f (h) ≈ f (gh) for
  all g\, h ∈ G\,\nwhere the approximation is in a common norm. Ulam aske
 d in 1940 whether\nsuch f can be approximated by an exact representation. 
 We prove that the\nanswer to the Ulam’s question is affirmative when the
  norm in question is any Schatten p-norm.
