There is a noninvertible linear map preserving a given function iff the function is constant on translates of a subspace. Any group preserving the function preserves the subspace. Hence it is often easy to isolate the cases in which such a noninvertible linear map can exist. For similarity invariants of matrices, this happens only for functions of the trace and for fuctions f satisfying f(X + λI) ≡ f(X). |
