Abstract:
We discuss relations between the theory of orthogonal polynomials, Hankel
determinants, and the unrestricted one-dimensional Toda chain. In particular,
we show that the equations of motion for the Toda chain are equivalent to
a Riccati equation for the Stieltjes function. We consider some examples of
the Stieltjes function with an explicit (hypergeometric and elliptic)
time dependence in detail.
Keywords:
integrable system, Toda chain, orthogonal polynomial.
