Invertibility of ideals in Prufer extensions
Carmelo Antonio Finocchiaro, Francesca Tartarone
Using the general approach to invertibility for ideals in ring extensions given by Knebush-Zhang, we investigate about connections between faithfully flatness and invertibility for…
A topological version of Hilbert's Nullstellensatz
Carmelo A. Finocchiaro, Marco Fontana, Dario Spirito
We prove that the space of radical ideals of a ring , endowed with the hull-kernel topology, is a spectral space, and that it is canonically homeomorphic to the space of the non…
Spectral spaces of semistar operations
Carmelo A. Finocchiaro, Marco Fontana, Dario Spirito
We investigate, from a topological point of view, the classes of spectral semistar operations and of eab semistar operations, following methods recently introduced by Finocchiaro a…
