In joint work with Joerg Rambau and Francisco Santos, I wrote a book on Triangulations,

Jointly with Raymond Hemmecke and Matthias Koeppe, I wrote a book on
the emerging theory of algebraic techniques in optimization. The title is
* Algebraic and Geometric Ideas in the Theory of Discrete
Optimization *and was published as volume 14 of the SIAM and
Mathematical Optimization Society joint Series on Optimization. We
hope to promote these algebraic ideas to more optimization
workers. The book shows several applications of algebra and geometry
to problems with non-linear constraints and hopefully demonstrates the
need to use algebraic ideas in the transition from linear discrete
optimization to nonlinear discrete optimization.

Both books are available as E-books, and often are freely available like that to all your students if your library subscribes to Springer and SIAM journals.

- Here is a
**detailed list of all my publications (up until June 2022).**(in PDF). -
Access here an annotated overview of all my research, with some e-copies of my papers collected by topic and described.
- Most of my papers since 2001 are available electronically through the Math ArXiv.
- I still keep a collection of some of my very old papers but I do not maintain the latest versions there anymore.
