Classical Zariski topology of modules and spectral spaces. II. (English) Zbl 1195.16003

This paper is a sequel to the authors’ previous study on a Zariski topology for the spectrum of prime submodules of a module over an associative ring [part I, Int. Electron. J. Algebra 4, 104-130 (2008; Zbl 1195.16002)]. The patch topology is considered, and using a characterization by M. Hochster [Trans. Am. Math. Soc. 142, 43-60 (1969; Zbl 0184.29401)], sufficient conditions are given for the spectrum of a module to be spectral – that is, homeomorphic to the prime spectrum of a commutative ring. In particular, Noetherian modules and Artinian modules over PI rings are spectral. It is further proved that the maximal spectrum of a Noetherian module is homeomorphic to the maximal spectrum of a commutative ring.
