Annihilator of $Ext^i_R(R/I,R)$
We investigate the higher divisorial ideal $D(I) := Ann(Ext^g_R(R/I,R))$ associated to an ideal $I$ of grade $g$. Our main focus is the containment problem $ D(I) \subseteq \overline{I}$. We show that this inclusion holds for broad classes of ideals, including unmixed ideals of finite projective dim
