Libraries and resellers, please contact cust-serv ams. See our librarian page for additional eBook ordering options. This book is about the interplay of computational commutative algebra and the theory of convex polytopes. It centers around a special class of ideals in a polynomial ring: the class of toric ideals. They are characterized as those prime ideals that are generated by monomial differences or as the defining ideals of toric varieties not necessarily normal. These applications lie in the domains of integer programming and computational statistics.

Among them, one of the most important topics is the correspondence to triangulations of convex polytopes. The purpose of this chapter is to explain these topics in detail.

First, we will explain convex polytopes, weight vectors, and monomial orders, all of which play a basic role in the rest of this chapter. Third, we will discuss the correspondence between the initial ideals of toric ideals and triangulations of convex polytopes, and the related ring-theoretic properties.

Finally, we will consider the examples of configuration matrices that arise from finite graphs or contingency tables, and we will use them to verify the theory stated above. If you would like to pursue this topic beyond what is included in this chapter, we suggest the books [ 2 , 7 ]. Skip to main content. This service is more advanced with JavaScript available.

Convex Polytopes and Gröbner Bases

Grobner Bases and Convex Polytopes. Bernd Sturmfels. This book is about the interplay of computational commutative algebra and the theory of convex polytopes. It centers around a special class of ideals in a polynomial ring: the class of toric ideals. They are characterized as those prime ideals that are generated by monomial differences or as the defining ideals of toric varieties not necessarily normal. The interdisciplinary nature of the study of Grobner bases is reflected by the specific applications appearing in this book. These applications lie in the domains of integer programming and computational statistics.
