Deformations of log Calabi–Yau pairs can be obstructed

Name: Work Video:
Duration: 3 min 30 s
Description: 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.
