    The entry unit of an adjunction had a big chunk of mixed itex+svg code at the beginning to display an adjunction. On my machine though the output of that code was ill typeset. So I have removed the code and replaced it by plain iTex encoding of an adjunction.

    (Just in case anyone deeply cares about the svg that was there. It’s still in the history. If it is preferred by anyone, it needs to be fixed first.)

    Mention that left adjoints are fully faithful iff the unit is invertible.

    Add mention of “lali” acronym, and duals. There might be a better page to have these (perhaps it’s even worth creating a separate page, since it would also be worth discussing their cancellation properties), but better somewhere than nowhere.

    I have hyperlinked “rali”.

    (First I thought it was a typo, but now I see that it’s intentional: rali lari lali rari – lirum larum Löffelstiel! :-)
