Riccati-type pseudo-potential approach to quasi-integrability of deformed soliton theories
Harold Blas
This review paper explores the Riccati-type pseudo-potential formulation applied to the quasi-integrable sine-Gordon, KdV, and NLS models. The proposed framework provides a unified…

Quasi-integrable KdV models, towers of infinite number of anomalous charges and soliton collisions
H. Blas, R. Ochoa, D. Suarez
We found, through analytical and numerical methods, new towers of infinite number of asymptotically conserved charges for deformations of the Korteweg-de Vries equation (KdV). It i…
