SUMMARY:Nam-Hoon Lee\, Mirror Pairs of Calabi-Yau Threefolds from Mirror Pairs of Quasi-Fano Threefolds
DESCRIPTION:     Speaker\n\n\nNam-Hoon Lee\nHongik Univ.\n\n\n\n\n\nWe present a new construction of mirror pairs of Calabi-Yau manifolds by smoothing normal crossing varieties\, consisting of two quasi-Fano manifolds. We introduce a notion of mirror pairs of quasi-Fano manifolds with anticanonical Calabi-Yau fibrations using conjectures about Landau-Ginzburg models. Utilizing this notion\, we give pairs of normal crossing varieties and show that the pairs of smoothed Calabi-Yau manifolds satisfy the Hodge number relations of mirror symmetry. We consider quasi-Fano threefolds that are some blow-ups of Gorenstein toric Fano threefolds and build 6518 mirror pairs of Calabi-Yau threefolds\, including 79 self-mirrors.
