   Format: MarkdownItexI've created an entry on [[Lindström's theorem]] and readjusted a bit the entries on [[predicate logic]], [[Löwenheim-Skolem theorem]]. I guess the most valuable thing in the entry is the link to free version of the Barwise-Feferman handbook. Hopefully somebody with a bird's eye view of the nlab knows a better context than 'foundation' for the entry. Any other improvement or expansion would be appreciated as well.

   Format: MarkdownItexI threw in two references in [[abstract model theory]]. Probably will throw in a link/entry to institutions one of these days, as they are the categorical way of doing abstract model theory.
