It's probably in a bunch of places, but I am not intimately familiar with the more recent introductory textbooks. But (since I had a certain amount to do with the writing of the nLab article): which technical details lost you, or where did you first find yourself getting lost? | |

| Dec 28, 2019 at 15:09 | comment | added | Hans | Thanks @ToddTrimble I have read the ncatlab article you sent before but I'm afraid I got lost in some of the technical details. Do you or anyone else know a more readable reference for the Adjoint Functor Theorem? | |

lower adjoints preserve sups
