Asit Saha is Assistant Professor (Research) in the Department of Mathematics, Sikkim Manipal Institute of Technology under Sikkim Manipal University, India. He received University Medal and Kiran Chandra Bhattacharya Medal for his MSc programme from University of North Bengal in 2005. He received his Ph.D. degree in 2016 from Visva-Bharati, India. He received Emerging Researcher Award in 2019 for his research contribution from Sikkim Manipal University. He is serving as an Editor for "The European Physical Journal Plus" since June, 2019. His research areas cover bifurcation, chaotic, hyperchaotic and multistability behaviours of waves in plasmas and various nonlinear fields. His group is known as the first to apply the theory of planar dynamical systems in plasma waves.Santo Banerjee was working as Associate Professor, in the Institute for Mathematical Research (INSPEM), University Putra Malaysia, Malaysia till 2020, and also a founder member of the Malaysia-Italy Centre of Excellence in Mathematical Science, UPM, Malaysia. He is now associated with the Department of Mathematics, Politecnico di Torino, Italy. His research is mainly concerned with Nonlinear Dynamics, Chaos, Complexity and Secure Communication. He is a Managing Editor of EPJ Plus (Springer).

• Preface. Introduction. Dynamical Systems. Waves in plasmas. Bifurcation of small amplitude waves in plasmas. Bifurcation of arbitrary amplitude waves in plasmas. Bifurcation analysis of supernonlinear waves. Chaos, multistability and stable oscillation in plasmas.
