A Weak Fano Threefold Arising as a Blowup of a Curve of Genus 5 and Degree 8 on ${\mathbb{P}}^3$

Abstract

This article constructs a smooth weak Fano threefold of Picard number two with small anti-canonical morphism that arises as a blowup of a smooth curve of genus 5 and degree 8 in ${\mathbb{P}}^3$. While the existence of this weak Fano was known as a numerical possibility in \cite{CM13} and constructed in BL12, this paper removes the dependencies on the results in \cite{JPR11} needed in the construction of BL12 and constructs the link in the style of ACM17.
