|title: ||On the relation between the full Kostant-Toda lattice and multiple orthogonal polynomials|
|authors: ||Barrios Rolanía, Dolores|
Foulquié Moreno, Ana Pilar
|keywords: ||Orthogonal polynomials|
|issue date: ||2011|
|abstract: ||The correspondence between a high-order non-symmetric difference operator with complex
coefficients and the evolution of an operator defined by a Lax pair is established.
The solution of the discrete dynamical system is studied, giving explicit expressions for
the resolvent function and, under some conditions, the representation of the vector of
functionals, associated with the solution for our integrable systems. The method of investigation
is based on the evolutions of the matrical moments.|
