Convex polytopes and linear algebra
نویسنده
چکیده
This paper defines, for each convex polytope ∆, a family Hw∆ of vector spaces. The definition uses a combination of linear algebra and combinatorics. When what is called exact calculation holds, the dimension hw∆ of Hw∆ is a linear function of the flag vector f∆. It is expected that the Hw∆ are examples, for toric varieties, of the new topological invariants introduced by the author in Local-global intersection homology (preprint alg-geom/9709011).

Piecewise Polynomial Functions, Convex Polytopes and Enumerative Geometry
0. Introduction. This paper explores some of the connections between the objects of its title. It is based on a new approach to McMullen’s polytope algebra, and on its relation with equivariant cohomology of toric varieties. In particular, we give another proof of a recent result of Fulton and Sturmfels, which identifies the polytope algebra with the direct limit of all Chow rings of smooth, co...
متن کاملBoundary Complexes of Convex Polytopes Cannot Be Characterized Locally
It is well known that there is no local criterion to decide the linear readability of matroids or oriented matroids. We use the set-up of chirotopes or oriented matroids to derive a similar result in the context of convex polytopes. There is no local criterion to decide whether a combinatorial sphere is polytopal. The proof is based on a construction technique for rigid chirotopes. These corres...
متن کاملBasic Properties of Convex Polytopes
Convex polytopes are fundamental geometric objects that have been investigated since antiquity. The beauty of their theory is nowadays complemented by their importance for many other mathematical subjects, ranging from integration theory, algebraic topology, and algebraic geometry (toric varieties) to linear and combinatorial optimization. In this chapter we try to give a short introduction, pr...

متن کاملNormal polytopes
In Section 1 we overview combinatorial results on normal polytopes, old and new. These polytopes represent central objects of study in the contemporary discrete convex geometry, on the crossroads of combinatorics, commutative algebra, and algebraic geometry. In Sections 2 and 3 we describe two very different possible ways of advancing the theory of normal polytopes to next essential level, invo...
