Intermittency transitions to strange nonchaotic attractors in a quasiperiodically driven Duffing oscillator
A. Venkatesan, M. Lakshmanan, A. Prasad +1
Different mechanisms for the creation of strange nonchaotic attractors (SNAs) are studied in a two-frequency parametrically driven Duffing oscillator. We focus on intermittency tra…

Role of Defects in Self-Organized Criticality: A Directed Coupled Map Lattice Model
Bosiljka Tadic, Ramakrishna Ramaswamy
We study a directed coupled map lattice model in two dimensions, with two degrees of freedom associated with each lattice site. The two freedoms are coupled at a fraction of la…

Maximal Lyapunov exponent at Crises
Vishal Mehra, Ramakrishna Ramaswamy
We study the variation of Lyapunov exponents of simple dynamical systems near attractor-widening and attractor-merging crises. The largest Lyapunov exponent has universal behaviour…
