Estimate on the real and imaginary parts of eigenvalues
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?
