摘要：In this report, we simply introduce the recent development of rogue waves (rogons) arising in deep ocean, nonlinear optics, Bose-Einstein condensates, plamas physics and even finance. Moreover, we discuss vector rogons/rogon-solitons of the multi-component nonlinear Schrodinger systems with with non-zero/mixed backgrounds, and analyze their strong and weak interactions, PT symmetry, and asymptotic behaviors.
