摘要 We investigate birationality of the anti-pluricanonical map Φ-m,the rational map defined by the anti-pluricanonical system |-mKX|,on weak Q-Fano 3-folds. We investigate birationality of the anti-pluricanonical map Φ-m,the rational map defined by the anti-pluricanonical system ｜-mKX｜,on weak Q-Fano 3-folds.
