Degree of canonical Fano 3-folds

Chen Jiang

Fudan University, Shanghai

Abstract: We show that the degree of a canonical weak Fano 3-fold is at most 72. This upper bound is optimal. Previously this is known for Gorenstein canonical weak Fano 3-folds proved by Prokhorov (known as Fano–Iskovskikh Conjecture). I will explain the proof for the Picard number 1 case (joint work with Haidong Liu and Jie Liu) and the general case (joint work with Tianqi Zhang and Yu Zou).
