| May 29, 2018 at 6:30 | comment | added | Denis Serre | Von Neumann's trace Inequality is in terms of singular values, not eigenvalues. Since $C^{1/2}A^{1/2}$ is not symmetric in general, its singular values do not equal its eigenvalues (they tend to be larger). Your second inequality is therefore false. | |
