   Also

   $\Re \;\coloneqq\; \iota_{sup} \iota_{inf} \circ \Pi_{inf}Pi_{sup}$

   and

   $\rightsquigarrow \;\coloneqq\; Disc_{sup} \circ \Pi_{sup}$

   Again, these may be repeated elsewhere.

   Format: MarkdownItexThanks for spotting these! All fixed now. Yes, this is spin-off material of the lecture notes _[[geometry of physics -- categories and toposes]]_ (where it is, currently, the last section [here](https://ncatlab.org/nlab/show/geometry+of+physics+--+categories+and+toposes#SolidToposes)). I have fixed it there now, too. Thanks again.
