Differential Equations Case: ISBN 3-05-501656-4, Quadratic Functionals in Variational Analysis
and Control Theory (by Werner Kratz), Akademie Verlag, Berlin, 1995.
Note: All the "continuous" results I talked about are contained in this
book.
Difference Equations Case: ISBN 0-7923-4277-1, Discrete Hamiltonian Systems: Difference Equations,
Continued Fractions, and Riccati Equations (by Calvin Ahlbrandt and
Allan Peterson), Kluwer, Boston, 1996.
Note: The discrete oscillation results I talked about are not in this book.
However, Chapter 8 is on my dissertation, and in particular the definition of
focal points for matrix-valued sequences is in there.
Dynamic Equations Case: ISBN 0-8176-4225-0, Dynamic Equations on Time Scales: An Introduction
with Applications (by Martin Bohner and Allan Peterson), Birkhäuser,
Boston, 2001.
Note: Chapter 7 contains results on symplectic dynamic systems as I mentioned them at the end of the talk.
