Effect of noise on the dynamics at the torus-doubling terminal point in a quadratic map under quasiperiodic driving.

Scaling regularities are examined associated with the effect of additive noise on a system driven by an external quasiperiodic force with the golden-mean frequency ratio near the terminal point of the torus-doubling bifurcation curve (TDT point). This point was studied in the context of the problem of the onset of a strange nonchaotic attractor on the basis… CONTINUE READING
