Abstract: The theoretical and experimental studies of nonlinear wave phenomena in mathematics, physics and engineering are advancing rapidly in recent years. In this talk, we report our analytical, numerical and experimental investigations on several nonlinear-wave topics including (i) universal weak interaction theory of solitary waves; (ii) soliton perturbation theory for general integrable equations; (iii) nonlinear light propagation in high-dimensional photonic periodic structures (both theory and experiments); and (iv) universally convergent iteration methods for solitary-wave computations in general nonlinear wave equations.
