چکیده
|
Let r =?n2n0rn be a standard graded ring, m bea nitely-generated graded r-module, and j be a homogeneousideal of r. in this work, we study the graded structure of the i-thlocal cohomology module of m, dened by a pair of ideals (r+; j),i.e. hir+;j (m). more precisely, we discuss the niteness propertyand vanishing of the graded components hir+;j (m)n. also, westudy the artinian property and tameness of certain submodulesand quotient modules of hir+;j (m).
