Query: On the eigenvalues of the spatial sign covariance matrix in more than
  two dimensions   We gather several results on the eigenvalues of the spatial sign covariance
matrix of an elliptical distribution. It is shown that the eigenvalues are a
one-to-one function of the eigenvalues of the shape matrix and that they are
closer together than the latter. We further provide a one-dimensional integral
representation of the eigenvalues, which facilitates their numerical
computation.
