Multicomplex solitons
Julia Cen, Andreas Fring
We discuss integrable extensions of real nonlinear wave equations with multi-soliton solutions, to their bicomplex, quaternionic, coquaternionic and octonionic versions. In particu…
Asymptotic and scattering behaviour for degenerate multi-solitons in the Hirota equation
Julia Cen, Andreas Fring
We construct all higher order conserved charges from a general two-dimensional zero curvature condition using a Gardner transformation. Employing two of those charges in the defini…
Integrable nonlocal Hirota equations
Julia Cen, Francisco Correa, Andreas Fring
We construct several new integrable systems corresponding to nonlocal versions of the Hirota equation, which is a particular example of higher order nonlinear Schrödinger equations…
Time-delay and reality conditions for complex solitons
Julia Cen, Francisco Correa, Andreas Fring
We compute lateral displacements and time-delays for a scattering processes of complex multi-soliton solutions of the Korteweg de-Vries equation.The resulting expressions are emplo…
Regularized degenerate multi-solitons
Francisco Correa, Andreas Fring
We report complex PT-symmetric multi-soliton solutions to the Korteweg de-Vries equation that asymptotically contain one-soliton solutions, with each of them possessing the same am…
Complex solitons with real energies
Julia Cen, Andreas Fring
Using Hirota's direct method and Baecklund transformations we construct explicit complex one and two-solutions to the complex Korteweg-de Vries equation, the complex modified Korte…
