##
Variational Analysis of Non-Lipschitz Spectral Functions

### James V. Burke and Michael L. Overton

We consider spectral functions f o lambda, where f is any
permutation-invariant mapping from C^n to R, and lambda is the
eigenvalue map from C^{n X n} to C^n, ordering the eigenvalues
lexicographically. For example, if f is the function
