Complete toric varieties with reductive automorphism group | Benjamin Nill
; | Date: |
28 Jul 2004 | Subject: | Algebraic Geometry; Combinatorics MSC-class: 14J45; 14J50; 14M25; 52B20 | math.AG math.CO | Abstract: | We give equivalent and sufficient criteria for the automorphism group of a complete toric variety, respectively a Gorenstein toric Fano variety, to be reductive. In particular we show that the automorphism group of a Gorenstein toric Fano variety is reductive, if the barycenter of the associated reflexive polytope is zero. Furthermore a sharp bound on the dimension of the reductive automorphism group of a complete toric variety is proven by studying the set of Demazure roots. | Source: | arXiv, math.AG/0407491 | Services: | Forum | Review | PDF | Favorites |
