Critical Slowing Down Enters PCS Recovery Research

PCS uses τrecovery ∝ (Lc−L)^−γ as a research hypothesis for increasing recovery time near a critical state.

As a complex system approaches a critical state, recovery from disturbance may slow. PCS expresses this critical-slowing-down hypothesis as τrecovery ∝ (Lc−L)^−γ, where Lc is a critical region to be estimated from data rather than a predetermined doomsday threshold.

Validation requires long time series, disturbance events, recovery indicators, and sensitivity analysis. The equation proposes a testable relation; it does not provide a deterministic date for catastrophe.
