Delta Constant

Definition

The delta constant, often represented by the symbol $$eta$$, is a mathematical constant that appears in the context of bifurcations in dynamical systems. It quantifies the rate at which the period of oscillation doubles as a system undergoes a transition from periodic behavior to chaotic behavior. This constant is crucial for understanding universal behaviors in nonlinear dynamical systems, especially when exploring the onset of chaos through period-doubling bifurcations.
