摘      要:

       In this talk, we first introduce the spectral stability and orbital stability of the elliptic function solutions for the focusing modified Korteweg-de Vries (mKdV) equation with respect to subharmonic perturbations and construct the corresponding breather solutions to exhibit the unstable or stable dynamic behavior. On the other hand,  by using Darboux-B\"acklund transformation, we construct multi-elliptic-localized wave solutions.  The asymptotic behavior of these multi-elliptic-localized wave solutions is also involved in this talk.
