| Sep 22, 2016 at 5:06 | comment | added | Nik Weaver | I think it's right. Try working out the $2 \times 2$ and $3\times 3$ cases if you don't believe me. | |
| Sep 22, 2016 at 0:36 | comment | added | NullOfMatrix | Thank you for your reply! But I do not think things could be that easy since there maybe interactions of $det(A)$ and $\sum A_{ij}$, and $A_{ij}$ have different signs which make the numerator term more complicated. But that is a good point! | |
