Abstract

‎Let $R$ be a Noetherian ring‎, ‎$I$ and $J$ two ideals of $R$‎, ‎$M$‎ ‎an $R$-module and $t$ an integer‎. ‎Let $S$ be a Serre subcategory‎ ‎of the category of $R$-modules satisfying the condition $C_I$ and‎ ‎$N$ be a finitely generated $R$-module with $\Supp_R N={\rm‎ ‎V}(\frak{a})$ for some $\frak{a}\in \tilde{{\rm W}}(I,J)$‎. ‎It is‎ ‎shown that if $\Ext_R^{j}(N‎, ‎H^{i}_{I,J}(M))\in S$ for all $i
