Non-normal Very Ample Polytopes and their Holes
In this paper, we show that for given integers h and d with h > 1 and d > 3, there exists a non-normal very ample integral convex polytope of dimension d which has exactly h holes.
متن کاملNormal generation of very ample line bundles on toric varieties ∗
Let A and B be very ample line bundles on a projective toric variety. Then, it is proved that the multiplication map Γ(A)⊗ Γ(B) → Γ(A⊗B) of global sections of the two bundles is surjective. As a consequence, it is showed that any very ample line bundle on a projective toric variety is normally generated. As an application we show that any ample line bundle on a toric Calabi-Yau hypersurface is ...
متن کاملConstructions for chiral polytopes
An abstract polytope of rank n is said to be chiral if its automorphism group has two orbits on flags, with adjacent flags lying in different orbits. In this paper, we describe a method for constructing finite chiral n-polytopes, by seeking particular normal subgroups of the orientation-preserving subgroup of n-generator Coxeter group (having the property that the subgroup is not normalized by ...

متن کاملConstructions and obstructions for extremal polytopes
In the fall of 2001, I was finishing my computer science undergrad studies and Martin Skutella suggested that I take the course " Linear optimization " , a course offered to beginning math grad students and taught by Prof. Günter Ziegler. Following his advice, my fellow student Roman Wagner and I took the course, and failed badly. We lacked the necessary linear algebra and so the teaching assis...
