Degenerations, fibrations and mirror symmetry
Fenglong You (University of Oslo)
Abstract: Given a Tyurin degeneration of a Calabi-Yau variety to a union of two quasi-Fano varieties, Doran-Harder-Thompson conjectured that the Landau-Ginzburg models of two quasi-Fano varieties can be glued to the mirror Calabi-Yau variety which admits a P^1-fibration. I will talk about a generalization of this conjecture to degenerations of quasi-Fano varieties. I will explain some evidence of this conjecture including a gluing formula for (relative) periods.
