  We look for solutions to derivative nonlinear Schrodinger equations built
upon solitons. We prove the existence of multi-solitons i.e. solutions behaving
at large time as the sum of finite solitons. We also show that one can attach a
kink at the begin of the sum of solitons i.e multi kink-solitons. Our proofs
proceed by fixed point arguments around the desired profile, using Strichartz
estimates.
