Bifurcations and transitions in the quasiperiodically driven logistic map
Surendra Singh Negi, Awadhesh Prasad, Ramakrishna Ramaswamy
We discuss several bifurcation phenomena that occur in the quasiperiodically driven logistic map. This system can have strange nonchaotic attractors (SNAs) in addition to chaotic a…

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…

Finite-time Lyapunov exponents of Strange Nonchaotic Attractors
Awadhesh Prasad, Ramakrishna Ramaswamy
The probability distribution of finite-time Lyapunov exponents provides an important characterization of dynamical attractors. We study such distributions for strange nonchaotic at…
