Query: Sturm intersection theory for periodic Jacobi matrices and linear
  Hamiltonian systems   Sturm-Liouville oscillation theory for periodic Jacobi operators with matrix
entries is discussed and illustrated. The proof simplifies and clarifies the
use of intersection theory of Bott, Maslov and Conley-Zehnder. It is shown that
the eigenvalue problem for linear Hamiltonian systems can be dealt with by the
same approach.
