Evaluate the product $\operatorname{tr}(AB)\operatorname{tr}(CB^{-1})$

92 Views Asked by At

Let $A,C$ be given positive semidefinite matrices, $B$ be an arbitrary positive definite matrix. How can I estimate the value of $\DeclareMathOperator{tr}{tr}\tr(AB)\tr(CB^{-1})$ ? Is that true $\tr(AB)\tr(CB^{-1}) \geq \tr(AC)$ ?
Thank you !
