| Dec 1, 2019 at 19:32 | comment | added | MTyson | In the nondiagonalizable case, it's not even true that all eigenvectors lie in the span of products of eigenvectors. Take $A$ and $B$ to be the $2$-by-$2$ Jordan block with eigenvalue $1$. Then $e_1\otimes e_1$ and $e_1\otimes e_2-e_2\otimes e_1$ are both eigenvectors of $A\otimes B$. The problem of computing the extra eigenvectors can always be reduced to the case where $A$ and $B$ are Jordan blocks by Jordanizing both. | |
