Factorization for the matrix-valued general Jacobi system on the full-line lattice

Tuncay Aktosun, Abdon E. Choque-Rivero, Vassilis G. Papanicolaou +2

The Jacobi system with matrix-valued coefficients and with the spectral parameter depending on a matrix-valued weight factor is considered on the full-line lattice. The scattering…

Soliton solutions to the Sawada--Kotera equation

Tuncay Aktosun, Abdon E. Choque-Rivero, Ivan Toledo +1

We consider the direct and inverse scattering problems for the third-order differential equation in the reflectionless case. We formulate a corresponding Riemann--Hilbert problem u…

Changing the discrete spectrum of the half-line matrix Schrödinger operator

Tuncay Aktosun, Ricardo Weder

We consider the matrix-valued Schrödinger operator on the half line with the general selfadjoint boundary condition. When the discrete spectrum is changed without changing the con…

Inverse scattering problem for the third-order equation on the line

Tuncay Aktosun, Ivan Toledo, Mehmet Unlu

We consider the third-order linear differential equation where the comp…

Soliton solutions associated with a class of third-order ordinary linear differential operators

Tuncay Aktosun, Abdon E. Choque-Rivero, Ivan Toledo +1

Explicit solutions to the related integrable nonlinear evolution equations are constructed by solving the inverse scattering problem in the reflectionless case for the third-order…
