摘 要: In this presentation, we will focus at beams with radially symmetric fields in transverse directions. Our investigation continues to a novel new concept of asymptotical stability. Highly oscillatory migration waves for applications will be explored. Physical concerns are once again placed before traditional mathematical arguments. Intensive auxiliary expansions and analysis will be carried out. It will be proven that, while appropriate constraints are reinforced, the asymptotical stability of the novel multiscale compact method remains affective. Computer experiments with laboratorial validations will be given to illustrate our conclusions. Our new multiscale computations are remarkably vibrating for various laser optics applications that were outlined by Bose and Einstein a century ago.
