摘要: By employing the complexification method and velocity resonant principle to $N$-solitons of the $(2+1)$-dimensional generalized Konopelchenko-Dubrovsky-Kaup-Kupershmidt (KDKK) equation, we obtain the soliton molecules, $T$-breather molecules, $T$-breather-$L$-soliton molecules and some interaction solutions when $N\leq6$. Dynamical behaviors of these solutions are discussed analytically and graphically. The method adopted can be effectively used to construct soliton molecules and $T$-breather molecules of other nonlinear evolution equations. The results obtained may be helpful for experts to study the related phenomenon in oceanography and atmospheric science.
