“…In recent years, the study of modules whose spectra space have a Zariski topology has grown in various directions. Some researchers have investigated the interplay between algebraic properties of a module and the topological properties of its spectrum (see for example [1,2,6,7,8,15,17,23,24,26,30,32]). Also the Zariski topology on the graded spectrum of graded rings in [33,34,35,36,37] was generalized in different ways to the graded spectrum of graded modules over graded commutative rings as in [3,4,13,14,33].…”
