The space of homogeneous preserving semistar operations on graded domains (Q2081194)

In this paper, the author studies the space of homogeneous preserving semistar operations on a graded ring \(R=\displaystyle\bigoplus_{\alpha\in \Gamma}R_{\alpha}\) graded by an arbitrary grading torsionless monoid \(\Gamma\). The main result states that the set \(SStar_{f, hp}(R)\) of finite type, homogeneous preserving semistar operations on \(R\), endowed with the Zariski topology, is a spectral space.
