Семинар лаборатории алгебраической геометрии: Gregory Sankaran (Bath)
Семинар состоится 6 декабря 2019 г. в 306 аудитории, начало в 17:00
На семинаре выступит Gregory Sankaran (Bath) с докладом Singularities of fourfold blowups
Using only elementary toric methods and facts about terminal quotient singularities and empty lattice simplices in dimension 4, we answer a question raised by Birkar, who asked for conditions under which a weighted blow-up of affine 4-space would not have terminal singularities.
