Causal Lyapunov Deficiency

Year: 2026
Type: preprint
Abstract: We develop a quantitative theory of nonanticipative comparison for filtered statistical experiments. For Gaussian observation towers, zero adapted deficiency is characterized exactly by prefix Fisher dominance, with constructive causal factorization and a filtered Fisher geometry. We also derive explicit chronology gaps, Lyapunov latency laws, and contact–Lyapunov phase transitions.
