Joyal and M. Tierney showed that the internal suplattices in the topos of sheaves on a locale are precisely the modules on that locale. Using a totally different technique, I shall show a generalization of this result to the case of (ordered) sheaves on a (small) quantaloid. Then I make a comment on module-equivalence versus sheafequivalence, using a recent observation of B. Mesablishvili and the notion of ‘centre’ of a quantaloid. | URI: | https://hdl.handle.net/10316/11353 | Rights: | openAccess |
