Abstract:
Let $(R, {\mathfrak {m}})$ be a commutative Noetherian local ring, and let $I$ and $J$ be two proper ideals of $R$. Let $M$ be a non-zero finitely generated $R-$module. We investigate the top local cohomology module $H_{I,J}^{{\text {dim}}M}(M)$. We get some results about attached prime ideals of the local cohomology module $H_{I,J}^{{\text {dim}}M}(M)$. As a consequence, we find that there exists a quotient $L$ of $M$ such that $H_{I,J}^{{\text {dim}}M}(M) \cong H_{I}^{{\text {dim}}M}(L)$. Also, we give the generalized version of the Lichtenbaum-Hartshorne Vanishing Theorem for local cohomology modules of a finitely generated module with respect to a pair of ideals.References
