NormalToricVarieties :: NormalToricVariety

NormalToricVariety -- the class of all normal toric varieties

Description

A normal toric variety corresponds to a strongly convex rational polyhedral fan in affine space. In this package, the fan associated to a normal d-dimensional toric variety lies in the rational vector space d with underlying lattice N = ℤd. The fan is encoded by the minimal nonzero lattice points on its rays and the set of rays defining the maximal cones (a maximal cone is not properly contained in another cone in the fan).

Caveat

By assumption, all normal toric varieties in this package have positive dimension.
