Quasi-Integrability and Some Aspects of SU(3) Toda Field Theory

In this talk I discuss results of our recent paper in which we have studied various properties of solitonic solutions of deformed SU(3) Toda field theories in (1 + 1) dimensions. The aim of that work was to check whether the results of scattering of such solitons supported our ideas on quasi-integrability. The deformations we considered preserved the symmetries which for other models were sufficient to guarantee their quasi-integrability. The results of our simulations had indeed led to the expected results, thus broadening the class of models which are quasi-integrable.
