Weakly integrable Camassa-Holm-type equations
Peilong Dong, Zhiwei Wu, Jingsong He
Series of deformed Camassa-Holm-type equations are constructed using the Lagrangian deformation and Loop algebra splittings. They are weakly integrable in the sense of modified Lax…

New Hierarchies of Derivative nonlinear Schrödinger-Type Equation
Zhiwei Wu, Jingsong He
We generate hierarchies of derivative nonlinear Schrödinger-type equations and their nonlocal extensions from Lie algebra splittings and automorphisms. This provides an algebraic e…
