We exhibit examples of pairs (X, D) where X is a smooth projective variety and D is an anticanonical reduced simple normal crossing divisor such that the deformations of (X, D) are obstructed. These examples are constructed via toric geometry.

Abstract
We exhibit examples of pairs (X, D) where X is a smooth projective variety and D is an anticanonical reduced simple normal crossing divisor such that the deformations of (X, D) are obstructed. These examples are constructed via toric geometry.File in questo prodotto:
