Title
Operator Reverse Monotonicity of the Inverse.
Abstract
In statistics and econometrics, the equivalence between matrix inequalities A >= B double left right arrow B(-1) >= A(-1) is used to obtain a lower bound on the variance matrix, where A, B are symmetric and positive definite. The same property holds for linear operators on Hilbert spaces that are bijective, self-adjoint, and positive definite. I give a short and elementary proof of this fact.
