Title: Solitonic, periodic and chaotic structures in plasmas

Abstract: The nonlinear structures, like solitonic, periodic, quasiperiodic and chaotic structures are observed in different unmagnetized and magnetized plasma systems. Bifurcations of nonlinear traveling waves are presented through direct and perturbative approaches. Considering an external periodic perturbation, periodic, quasiperiodic and chaotic structures are presented. Depending on the collisional frequency, a dynamical transition is observed from quasiperiodic motion to limit cycle oscillation in collisional plasmas.
