Estimate for the operator $A A_D^{-1}$

From the identity $(AA_D^{-1}\phi,f)_{L_2}=(\phi,f)_{L_2}$ it follows that $$\vert (\phi, (AA_D^{-1})^* f)_{L_2}\vert \leqslant \Vert \phi\Vert _{L_2}\Vert f\Vert _{L_2}\quad \forall \phi\in L_2(O).$$ …

Estimate for the operator $A A_D^{-1}$

Let $O\subset\mathbb{R}^d$ be a bounded domain of the class $C^{1,1}$ (or $C^2$ for simplicity). Let the operator $A_D$ be formally given by the differential expression $A=-\operatorname{div}g(x)\nabl …
