- Attractor Selection and Basin Control
- Dynamical systems and physics: Chemical reactors with bistability (e.g., substrate inhibition or autocatalysis producing multiple equilibrium concentrations); climate systems with alternative stable states (ice-covered and ice-free poles, monsoon and no-monsoon regimes); mechanical systems with potential energy landscapes (ball rolling in a multi-well potential), domains Scheffer (2009) synthesizes in his treatment of critical transitions in nature and society.
This sourceCross-disciplinary synthesis identifying critical slowing-down, rising variance/autocorrelation, and flickering as generic early-warning precursors of regime shifts in ecosystems, climate, and markets (systems with multiple stable states / shifting basins). SUPPORTS marker 053.

- Criticality
- Ecology: ecosystem regime shifts (lake eutrophication, coral reef bleaching, savanna-to-desert transitions) approached as the system nears a critical control-parameter value; the use of critical slowing-down, rising variance, rising autocorrelation, and flickering as early-warning indicators of impending regime shift, an empirical research program Scheffer et al. (2009) consolidated in their Nature synthesis of early-warning signals.

- Regime Change
- A regime change is the discontinuous shift of a system from one stable operating regime to a qualitatively different one, where the same external inputs produce fundamentally different responses on either side of the transition, as Scheffer (2009) develops in his canonical treatment of critical transitions in nature and society.

- This pattern spans dynamical systems (bifurcations, attractor switching, hysteresis), climate science (ocean circulation tipping points, ENSO regime shifts), ecology (alternative stable states in lakes and grasslands), macroeconomics (monetary policy regimes, inflation equilibria), finance (volatility regimes, market microstructure transitions), and political science (revolutions, constitutional upheavals), with this cross-domain breadth surveyed by Scheffer et al. (2009) in their Nature review of early-warning signals across natural and social systems.
This sourceCross-domain review demonstrating that regime shifts in climate, ecosystems, finance, and physiological systems share a common bifurcation signature, justifying shared analytic toolkit.
- Signals of regime change include early warning indicators: rising variance, increased autocorrelation (slowing recovery from perturbations), and bifurcation instabilities visible in spectral analysis, as Scheffer et al. (2009) document in their synthesis of early-warning signals for critical transitions.
This sourceSynthesizes the canonical early-warning signatures of regime change—rising variance, increased autocorrelation (critical slowing down), and flickering—across diverse complex systems.

- Resilience
- The mechanism determines both the probability of successful resilience and its timescale. Finite envelope. Resilience is bounded; the system has limits beyond which it transitions to a different regime or fails, as Scheffer (2009) catalogs in Critical Transitions in Nature and Society

- Reversibility Horizon
- This creates a dynamic instability: decision-makers extrapolate a gradual horizon and then are shocked when it accelerates or jumps—a regime-shift dynamic Scheffer et al. (2009) characterize through early-warning signals for critical transitions.
