A Mathematical Modeling Approach from Nonlinear Dynamics to Complex SystemsThis book collects recent developments in nonlinear and complex systems. It provides up to date theoretic developments and new techniques based on a nonlinear dynamical systems approach that can be used to model and understand complex behavior in nonlinear dynamical systems. It covers symmetry groups, conservation laws, risk reduction management, barriers in Hamiltonian systems, and synchronization and chaotic transient. Illustrating mathematical
