Rank two Weak Fano bundles on Fano threefolds of Picard rank one
Takeru Fukuoka, Wahei Hara, Daizo Ishikawa
We classify rank two vector bundles on a Fano threefold of Picard rank one whose projectivizations are weak Fano. We also prove the existence of examples for each case of the class…
Rank two weak Fano bundles on del Pezzo threefolds of degree five
Takeru Fukuoka, Wahei Hara, Daizo Ishikawa
This paper classifies rank two vector bundles on a del Pezzo threefold of degree five whose projectivizations are weak Fano. This classification is then used to determine prope…
Classification of rank two weak Fano bundles on del Pezzo threefolds of degree four
Takeru Fukuoka, Wahei Hara, Daizo Ishikawa
We classify rank two vector bundles on a given del Pezzo threefold of degree four whose projectivizations are weak Fano into seven cases. We also give an example for each of these…
Refinement of the classification of weak Fano threefolds with sextic del Pezzo fibrations
Takeru Fukuoka
We refine the classification of weak Fano threefolds with sextic del Pezzo fibrations by considering the Hodge numbers of them. By the refined classification result, such threefold…
Relative linear extensions of sextic del Pezzo fibrations
Takeru Fukuoka
In this paper, we study a sextic del Pezzo fibration over a curve comprehensively. We obtain certain formulae of several basic invariants of such a fibration. We also establish the…
On the existence of almost Fano threefolds with del Pezzo fibrations
Takeru Fukuoka
By Jahnke-Peternell-Radloff and Takeuchi, almost Fano threefolds with del Pezzo fibrations were classified. Among them, there exists 10 classes such that the existence of members o…
