WebWeyl–von Neumann theorem. In mathematics, the Weyl–von Neumann theorem is a result in operator theory due to Hermann Weyl and John von Neumann. It states that, after the addition of a compact operator ( Weyl (1909)) or Hilbert–Schmidt operator ( von Neumann (1935)) of arbitrarily small norm, a bounded self-adjoint operator or unitary ...
