| 소개 및 안내사항Content | On birationally solid Fano 3-fold hypersurfaces Fano 3-folds that are embedded as (quasismooth) hypersurfaces in weighted projective 4-spaces are classified and they form 130 families. Among them 95 families consist of Fano 3-fold weighted hypersurfaces of Fano index 1, and Cheltsov-Park proved that they are all birationally rigid. Recently, Abban-Cheltsov-Park showed that none of Fano 3-fold weighted hypersurfaces of Fano index at least 2 is birationally rigid. The aim of this talk is to explain birational properties of these Fano 3-fold weighted hypersurfaces of Fano index at least 2, and explain that some of them are birationally solid which is a notion weaker than birational rigidity. ★ Pre-registration is certainly required, please visit https://cgp.ibs.re.kr/ |
