Toric ideals, real toric varieties, and the moment map

This is a tutorial on some aspects of toric varieties related to their potential use in geometric modeling. We discuss projective toric varieties and their ideals, as well as real toric varieties and the moment map. In particular, we explain the relation between linear precision and the moment map.

Symplectic Toric Manifolds

Foreword These notes cover a short course on symplectic toric manifolds, delivered in six lectures at the summer school on Symplectic Geometry of Integrable Hamiltonian Systems, mostly for graduate students, held at the Centre de Recerca Matemàtica in Barcelona in July of 2001. The goal of this course is to provide a fast elementary introduction to toric manifolds (i.e., smooth toric varieties)...

Topology of real toric surfaces

We determine the homeomorphism type of the set of real points of a smooth projective toric surface. The purpose of this note is to prove the following topological classification of real toric surfaces. Theorem [De1, Proposition 4.1.2.] Let X = X(∆) be a smooth projective toric surface. If X is isomorphic to an even Hirzebruch surface F2a, for some integer a ≥ 0, then X(R) is homeomorphic to S ×...
