The same object — a Schur-complement conditional, shrunk toward independence by a damping parameter — has appeared in two 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 actually uses Schur complements. The dashed lines mark damping's arrival in finance (Nov 2022) and in spatial statistics (Sep 2024). Hover for details; click to open. Dates marked ⚠ are month-approximate.
