  The 2022 logic blog has concentrated on the connections of group theory and
logic. It discusses Gardam's 2021 refutation of the Higman/ Kaplansky unit
conjecture, and its connections to logic and to computation. The rest is about
topological groups of various kinds, in particular a computational theory of
tdlc groups, and a duality between locally Roelcke precompact groups and
certain countable structures called meet groupoids.
