Expository
Polished expository articles intended to explain concepts, methods, or results clearly and self-containedly, with an emphasis on exposition rather than novelty.
Notes
Working notes, informal derivations, calculations, and intermediate results. These posts are exploratory in nature and reflect ongoing thought rather than polished exposition.
