摘    要：In this talk, we introduce several types of nonlinear waves appearing many fields of nonlinear science, such as fluid mechanics, nonlinear optics, Bose-Einstein condensates, plasma physics, finance, and etc. Moreover, we discuss the formation and dynamics of some significant nonlinear wave stuctures (e.g., peakons, rogue waves) in the generalized nonlinear Schrodinger equations with complex/real potentials via the analytical, numerical, and deep learning methods.
