Can Strange Nonchaotic Dynamics be induced through Stochastic Driving?
Awadhesh Prasad, Ramakrishna Ramaswamy
Upon addition of noise, chaotic motion in low-dimensional dynamical systems can sometimes be transformed into nonchaotic dynamics: namely, the largest Lyapunov exponent can be made…
Collision and symmetry-breaking in the transition to strange nonchaotic attractors
Awadhesh Prasad, Ramakrishna Ramaswamy, Indubala I. Satija +1
Strange nonchaotic attractors (SNAs) can be created due to the collision of an invariant curve with itself. This novel ``homoclinic'' transition to SNAs occurs in quasiperiodically…
Characteristic distributions of finite-time Lyapunov exponents
Awadhesh Prasad, Ramakrishna Ramaswamy
We study the probability densities of finite-time or \local Lyapunov exponents (LLEs) in low-dimensional chaotic systems. While the multifractal formalism describes how these densi…
