WebA matrix norm on M n is said to be weakly unitarily-invariant if conjugating a matrix by a unitary U does not change the norm. That is, Many commonly-used matrix norms are weakly unitarily-invariant, including the operator norm, Frobenius norm, numerical radius, Ky Fan norms and Schatten p-norms.
