Revisiting Ueda oscillator: Emergence of chaos at ultra-low driving frequencies

The degenerate forced Duffing oscillator, characterized by zero linear stiffness and nonzero cubic stiffness, which is commonly known as the Ueda oscillator, has long been regarded as a canonical benchmark in nonlinear dynamics and chaos theory. In his seminal work, Ueda demonstrated the emergence of chaos at a dimensi...
