“Manifolds with two projective bundles structures”

Abstract
Having a projective bundle structure makes a variety rather special, so having two different projective bundle structure should be quite uncommon, especially if we assume that the Picard group of the variety is two-dimensional (in this case the variety is Fano).
On the other hand, such varieties appear in many different – apparently unrelated – contexts, for instance in the study of dual defective varieties, flops and horospherical varieties; therefore classification results for these varieties are very interesting.
In my talk I will review old and new results about this problem.
