Abstract: This is part two of the combinatorics of orthogonal
polynomials. I will discuss the connection between the Bethe Ansatz,
Chebyshev type orthogonal polynomials and perturbed uniform Motzkin
paths in a strip. This leads to a `matrix diagonalization` proof of
Viennot's path theorem. If time permits I'll discuss the
generalisation to N-path systems. This time there will be more linear
algebra than combinatorics.
