I am writing this month about the papers and results I have most enjoyed or thought about this year. As always with such lists, exclusion is not meant to indicate that I have a poor opinion of a given work or paper.

The first post is about Neeman’s fantastic counterexample to some conjectures in negative K-theory.

The second post is about the filtered circle(s) of Moulinos–Robalo–Toën and Raksit.
