| Mar 17, 2022 at 12:34 | comment | added | Sascha | The previous question was too general so that it was false in general and true in the special case of $B$ self-adjoint. The new question is a special case of the previous question, but hopefully true even if $B$ is not self-adjoint. The self-adjoint case is already proven. | |

| Mar 17, 2022 at 12:20 | comment | added | Sascha | @KurtG. [1] is about block-matrices, the question has been answered when $B$ is self-adjoint and shown to be false when $B$ is not self-adjoint (in general). Here, I consider now the case that $A$ and $B$ are not block matrices but matrices, in which case the statement still seems to hold, even when $B$ is not hermitian. | |
