The same object, a Schur-complement conditional shrunk toward independence by a damping parameter, has appeared in three fields so far. One lane per field; events at their earliest public date (preprint or blog post, not journal acceptance); scope is strict: only work that uses Schur complements. The dashed lines mark damping's arrival in finance (Nov 2022), in spatial statistics (Sep 2024) and in decentralised finance (Jun 2026). Hover for details; click to open. Dates marked ⚠ are month-approximate.
