Abstract

Let R=nN0RnR = \bigoplus_{n \in \mathbb{N}_0} R_n be a Noetherian homogeneous ring with local base ring (R0,m0)(R_0, \mathfrak{m}_0) and let MM and NN be finitely generated graded RR-modules. Let i,jN0i,j\in\mathbb{N}_0. In this paper we will study Artinianess of Γm0R(HR+i(M,N)),Hm0R1(HR+i(M,N)),HR+i(M,N)/m0HR+i(M,N),HR+j(M,Hm0Ri(N)),Hm0Rj(M,HR+i(N))\Gamma_{\mathfrak m_0R}(H_{R_+}^i(M,N)), H_{\mathfrak m_0R}^1(H_{R_+}^i(M,N)), H_{R_+}^i(M,N)/{\mathfrak m_0}H_{R_+}^i(M,N), H_{R_+}^j(M,H_{\mathfrak m_0R}^i(N)), H_{\mathfrak m_0R}^j(M,H_{R_+}^i(N)), where R+R_+ denotes the irrelevant ideal of RR.
