【摘 要】
：
Nonlocal symmetries related to the B?cklund transformation(BT)for the modified KdV-sine-Gordon(mKdV-SG)equation are obtained by requiring the mKdV-SG equation and its BT form invariant under the infinitesimal transformations.Then through the parameter exp

Vector kink-dark complex solitons in a three-component Bose-Einstein condensate
We investigate kink-dark complex solitons(KDCSs)in a three-component Bose–Einstein condensate(BEC)with repulsive interactions and pair-transition(PT)effects.Soliton profiles critically depend on the phase differences between dark solitons excitation eleme
