different discrete models of population dynamics of certain insects have been investigated under various feasible conditions within the framework of nonlinear dynamics. evolutionary phenomena are discussed through bifurcation analysis leading to chaos. some tools of nonlinear dynamics, such as lyapunov characteristic exponents (lce), lyapunov numbers, correlation dimension, etc. are calculated ...

We review recent developments in the research of nonlinear and nonequilibrium phenomena solids focusing on their geometrical aspects. start with introducing basic concepts phases Bloch electrons Floquet theory for periodically driven systems. Then we attempts to engineer topological matters such as graphene, magnets, superconductors irradiated circularly polarized light. next a bulk photovoltai...
