Toric degenerations of minuscule Schubert varieties and mirror symmetry (JAPANESE)
三浦 真人 氏 (東大数理)
Toric degenerations of minuscule Schubert varieties and mirror symmetry (JAPANESE)
[ 講演概要 ]
Minuscule Schubert varieties admit the flat degenerations to projective
Hibi toric varieties, whose combinatorial structure is explicitly
described by finite posets. In this talk, I will explain these toric
degenerations and discuss the mirror symmetry for complete intersection
Calabi-Yau varieties in Gorenstein minuscule Schubert varieties.
