摘要

Let G be a group with identity e. Let \(\Re \) be a G-graded commutative ring and \(\Im \) a graded \(\Re \) -module. The graded primary-like spectrum \( PL.Spec_{g}(\Im )\) P L . S p e c g ( ) is defined to be the set of all graded primary-like submodules of \(\Im \) satisfying the gr-primeful property. The Zariski topology on \(PL.Spec_{g}(\Im )\) P L . S p e c g ( ) , denoted by \(PL.\tau ^{g}\) P L . τ g , is described by taking the set PL- \(\eta (\Im )=\{PL\) η ( ) = { P L - \(V_{\Im }^{g}({\mathcal {C}})\mid {\mathcal {C}}\) V g ( C ) C is a graded submodule of \(\Im \}\) } as the set of closed sets of \(PL.Spec_{g}(\Im ),\) P L . S p e c g ( ) , where PL- \(V_{\Im }^{g}({\mathcal {C}})=\{P\in PL.Spec_{g}(\Im )\mid Gr((P:_{\Re }\Im ))\supseteq Gr(({\mathcal {C}}:_{\Re }\Im ))\}.\) V g ( C ) = { P P L . S p e c g ( ) G r ( ( P : ) ) G r ( ( C : ) ) } . In this paper, we study the irreducible and irreducible components closed subsets of ( \(PL.Spec_{g}(\Im )\) P L . S p e c g ( ) , \(PL.\tau ^{g}\) P L . τ g ) and we give a result about Noetherianness of the graded primary-like spectrum of a graded module. Also, we study the topological space ( \(PL.Spec_{g}(\Im )\) P L . S p e c g ( ) , \( PL.\tau ^{g}\) P L . τ g ) from the point of view of spectral space.
