Fano Symmetric Varieties with Low Rank

open access: yesPublications of the Research Institute for Mathematical Sciences, 2012
The symmetric projective varieties of rank one are all smooth and Fano by a classical result of Akhiezer. We classify the locally factorial (respectively smooth) projective symmetric G -varieties of rank 2 that are Fano. When

Toric Fano varieties and birational morphisms

open access: yes, 2001
In this paper we study smooth toric Fano varieties using primitive relations and toric Mori theory. We show that for any irreducible invariant divisor D in a toric Fano variety X, we have $0\leqρ_X-ρ_D\leq 3$, for the difference of the Picard numbers of X and D.

Combinatorial studies of Fano varieties via toric embeddings [PDF]

open access: yes
This thesis contributes to the development of combinatorial methods for the study of geometrical invariants of Fano varieties. In the first part, we provide a combinatorial criterion for a non-degenerate toric complete intersection to be normal and ...

Topics in Fano Varieties and Singularities

open access: yes, 2018
In this thesis, we look at several problems in two areas of algebraic geometry: singularities and Fano varieties. From the singularities side, we examine the relationship between local fundamental groups and étale covers of the regular locus of a normal ...

All complete intersection varieties are Fano visitors

open access: yes, 2018
We prove that the derived category of a smooth complete intersection variety is equivalent to a full subcategory of the derived category of a smooth projective Fano variety.

Birational Geometry of 3-fold Mori Fibre Spaces [PDF]

open access: yes, 2004
We study the geography and birational geometry of 3-fold conic bundles over P\(^2\) and cubic del Pezzo fibrations over P\(^1\).
