The nucleus of an adjunction

Ross Street – 6 May 2020

This is a report on a preprint of Dusko Pavlovic and Dominic Hughes. The paper is a rich mine for gems (previously unseen by me) shining light on adjunctions and monads. In particular, it adds to both Theorem 11 of [3] FTM and the Applegate-Tierney tower [SLNM#80].
