Stabilityä
Stabilityä is a theoretical concept used in dynamical systems and control theory to describe a form of stability that remains robust under time-varying disturbances and multi-scale feedback. It extends classical notions of stability by explicitly addressing environments that change over time and by incorporating adaptive responses within the system’s structure. The term combines stability with the ligature æ to suggest a synthesis of resilience and adaptability across contexts.
A system around a reference state x* is said to have stabilityä if, for a broad class
Stabilityä generalizes several existing ideas, including asymptotic stability, input-to-state stability, and robust stability, by emphasizing both
Applications appear in advanced control design, ecological modeling, economic networks, and climate or energy systems. Verifying
