ABSTRACT:   It has been first observed by Rødland in 2000 that two different Calabi-Yau manifolds might have the same mirror. This is related to the fact that in the B-model the Picard Fuchs equation sometimes admits more than one point of Maximal Unipotent Monodromy. By homological mirror symmetry this is also related to the existence of derived equivalent pairs of Calabi-Yau manifolds.  We will discuss this phenomenon on some examples from different points of view. Beside derived categories, these will include, toric degenerations, gauged linear sigma models, stability conditions and motives.
 
Everybody interested is warmly welcomed to attend.

 
Best regards,
Andrea, Alessandro and Michele
