added answers to modified items 2 and 3

| Jul 19, 2011 at 16:26 | comment | added | Sunni | Yes, so I see that item 2 is not correct. | |
| Jul 19, 2011 at 16:05 | comment | added | Willie Wong | Modify the example by Tsuyoshi Ito: take $A = I, C = I/2$, $B = 0$, $n=2$, and $k = 1$. The LHS is $1\times 1 = 1$. The right hand side is $1 \times 1/2 = 1/2$. | |
| Jul 19, 2011 at 15:57 | comment | added | Sunni | +1 for your partial solution. I think I made a typo in Item 2, $k$ in the left hand side should be $2k$. When $k=n$, obviously item 2 is correct. | |
