An Update on the Classification of Rank 2 Weak Fano Threefolds
An Update on the Classification of Rank 2 Weak Fano Threefolds
In this paper, an update on the classification of smooth weak Fano threefolds with Picard number two and small anti-canonical maps is given. Geometric constructions are provided for previously open numerical cases by blowing up certain curves on smooth Fano threefolds of Picard number one. This paper provides updated tables …
