Abstract:
The correspondence between dynamics of q-Toda and q-Volterra equations for the coefficients of the Jacobi operator and its resolvent function is established. The main ingredient are orthogonal polynomials which satisfy an Appell condition, with respect to the q difference operator D_q and a Lax Theorem for the point spectrum of the Jacobian operator associated with these equations.
