If we consider two symmetric positive definite matrices $A$ and $B$ with the ordering $A>B$, i.e., $A-B>0$ is positive (semi-)definite, does then
$B^{-1} A B^{-1} > A$
hold? It can be shown that
$B^{-1}AB^{-1}>B^{-1}>A^{-1}$ holds because $A>B$ is equivalent to $A^{-1}
Does anyone know whether also $B^{-1} A B^{-1} > A$ holds?
