Stability theoryRelated: Parameter changes can destroy stability or create new stable states.
Nonlinear systemRelated: Changing a parameter can create or destroy equilibria and cycles.
Periodic orbitRelated: Bifurcations can create, destroy, or change the stability of periodic orbits.
Julia setRelated: Changing a map’s parameter can alter Julia-set connectivity and geometry.
Dynamical systems theoryRelated: A parameter change can create or destroy equilibria and attractors.
Artur AvilaRelated: Avila’s work clarifies how dynamical behavior changes across parameter space.
