Introduced a requirement that avoids the trivial counter-example B = C = 0

| Aug 29, 2013 at 18:53 | comment | added | Joel Wallman | Thanks, I guess that is the obvious counterexample. I've edited the question to reflect some of the extra structure in my problem that avoids this. | |
| Aug 29, 2013 at 18:50 | comment | added | Carlo Beenakker | no, just take as a counterexample $\Sigma_B=0=\Sigma_C$. Then $A+B=A$ and $C+D=D$, so your assumption fails unless $U_1=U_2$ and $V_1=V_2$. | |
