| Sep 2, 2013 at 17:22 | comment | added | Yemon Choi | @Craven use the matrix that diagonalizes B to conjugate A to a matrix of the form D+C' where C' is conjugate to C and hence has the same spectral data. Then apply Gershforin. If this point remains unclear then perhaps you could take further questions to math.stackexchange.com | |
| Sep 2, 2013 at 12:24 | comment | added | Not Buying It | I can't follow, assuming B is self adjoint I write A=PDP^+C so A-PDP^=C, the only way I see at the moment to arrive to your conclusion is by assuming that A is at least triangularizable under the same unitary transformation P, can you clarify? | |
