Jacobi-Perron algorithms, bi-orthogonal polynomials and inverse scattering problems
The purpose of this note is to construct 3rd order linear difference operators by Jacobi-Perron algorithms as a generalization of continued fractions and to prove an equivalence between linear evolution equations of spectral densities and Lax type equations.
