| Dec 1, 2023 at 20:28 | comment | added | Ali Taghavi | @SpencerKraisler My apology for my late repley. To be honest the answer I provided in the post was based on immediate computation. It was not based on a reference on Stein equation. at the time of answering I was not aware of the special terminology, i.e stein equation, for such equation. So I do not know any resource on the topic. I will come back you if I find some resources | |

| May 20, 2018 at 20:53 | comment | added | Ali Taghavi | @Mahdi Thanks for your comment. Yes you are completely right. the spectrum is invariant under cyclic permutation. But our extra assumption $PQ=QP$ implies that the permutation I used is actualy a cyclic permutation. Right? | |
| May 20, 2018 at 20:27 | comment | added | Mahdi - Free Palestine | I can't follow this "the spectrum of the solution $X={(P-Q)}^{1/2}T P^{-1/2}$ is equal to the spectrum of $T{(P-Q)}^{1/2}P^{-1/2}$ because $AB$ and $BA$ have the same spectrum". The later statement implies just that the spectrum of the product of some matrices is invariant under cyclic permutation, not every permutation. am I missing something? | |
