Jul 17, 2017 at 7:14 comment added Valery Isaev @მამუკაჯიბლაძე Yes, I'm familiar with that. It would be nice to see a more general development of the theory in this setting, but I'm also fine with the impredicative approach.
Jul 17, 2017 at 7:08 comment added მამუკა ჯიბლაძე The keyword for an "even more constructive" approach is formal topology

Jul 17, 2017 at 6:22 comment added Valery Isaev @AndreasBlass Yes, you're right. I've updated the post.
Jul 17, 2017 at 6:22 comment added Valery Isaev @JamesSmith I've seen this paper. Discrete locales are defined there in the same way as I did in my second question. I think I also saw this definition in another paper. That was one of the reasons for this questions since it seems that this definition is not very natural in a constructive setting.
Jul 17, 2017 at 4:05 comment added Andreas Blass Terminological complaint: In traditional (pointy) topology and, as far as I know, also in localic topology, "open map" has a more general meaning than what you defined here. An continuous map of topological spaces is said to be open if the image of every open set is open.
Jul 16, 2017 at 17:33 comment added James Smith I am not sure whether this paper is entirely relevant and it may have been one of Steve Vicker's papers that you have read already but, just in case, there is Continuity is Geometricity.
Jul 16, 2017 at 15:23 comment added Valery Isaev Yes, I've read some of his papers, but I'm looking for more basic and foundational facts such as comparison of different definitions of discreteness and other properties.
Jul 16, 2017 at 15:15 comment added Andrej Bauer Have you looked into the writings of Steve Vickers?
