### Özet

Triangulations appear everywhere, from volume computations and meshing to algebra and topology. This book studies the subdivisions and triangulations of polyhedral regions and point sets and presents the first comprehensive treatment of the theory of secondary polytopes and related topics.A central theme of the book is the use of the rich structure of the space of triangulations to solve computational problems (e.g., counting the number of triangulations or finding optimal triangulations with respect to various criteria), and to establish connections to applications in algebra, computer science, combinatorics, and optimization.With many examples and exercises, and with nearly five hundred illustrations, the book gently guides readers through the properties of the spaces of triangulations of "structured" (e.g., cubes, cyclic polytopes, lattice polytopes) and "pathological" (e.g., disconnected spaces of triangulations) situations using only elementary principles.

De Loera (Univ. of California, Davis), Rambau (Univ. of Bayreuth, Germany), and Santos (Univ. of Cantabria, Spain) refer to triangulations as decompositions of a region of Euclidean space into simplices (i.e., line segments, triangles, tetrahedra, etc.) with vertices lying in a predetermined set. Focusing on the structure of the set of all possible triangulations (subject perhaps to some hypothesis), the current study sits at the threshold of geometry and combinatorics; the familiar story of Catalan numbers and polygon triangulations offers a tiny taste of this rich story. While basic objects here possess concreteness offering terra firma to students still struggling with abstraction, the central theorem (due to Gelfand, Kapranov, and Zelevinsky) only dates to 1989, so the present elaboration carries readers to the frontiers of research. Similar to knot theory, this makes triangulations perfect for an undergraduate capstone course. It is unusual to find such a leisurely, generous exposition of a new subject, as replete with illustrations as contemporary calculus textbooks. Chapter 8 provides the computer scientist's vantage. Triangulations do have practical applications (graphics, differential equation solvers) and material here does have practical implications, but this volume concentrates on basic theory, veering occasionally into mathematical applications, e.g., real algebraic geometry and Hilbert's 16th problem.
