Periodic solutions of the DABO equation as a sum of repeated solitons

It is shown that the periodic solution of the non-linear DABO equation can be written as an infinite sum of an equally spaced row of identical Lorentzian solitons. This may be considered as a generalisation of a similar result which has been found for the KdV equation and is related to the clean-interaction properties of colliding solitons under non-linear coupling.
