Discrete Hamiltonian Systems : Difference Equations, Continued Fractions, and Riccati Equations (Kluwer Texts in the Mathematical Sciences, Vol 16)

In particular, the material of the chapters on continued fractions (Chapter 2), symplectic systems (Chapter 3), and discrete variational theory (Chapter 4) summarize recent literature. Similarly, the material on transforming Riccati equations presented in Chapter 3 gives a self-contained unification of various forms of Riccati equations.
