Spaces of subobjects as spectral spaces

Federico Campanini, Carmelo Antonio Finocchiaro

We study natural topologies on spaces of subobjects of a fixed object in a suitable category, with the aim of determining when these spaces are spectral. A central step in our appr…

A pretorsion theory for right groups

Alberto Facchini, Carmelo Antonio Finocchiaro

Let $S$ be a right group. Then there exist two congruences $\sim$ and $\equiv$ on $S$ such that $S$ is the product of its quotient semigroups $S / \sim$ and $S / \equiv$ , where $S/…
