Some examples of log Fano structures on blow-ups along subvarieties in products of two projective spaces
Toru Tsukioka
We consider the problem to determine which blow-ups along subvarieties in products of two projective spaces are log Fano. By describing the nef cones of such blow-ups with special…
On weak Fano manifolds with small contractions obtained by blow-ups of a product of projective spaces
Toru Tsukioka
We consider weak Fano manifolds with small contractions obtained by blowing up successively curves and subvarieties of codimension 2 in products of projective spaces. We give a cla…
On the minimal length of extremal rays for Fano 4-folds
Toru Tsukioka
The minimum of intersection numbers of the anti-canonical divisor with rational curves on a Fano manifold is called pseudo-index. It is expected that the intersection number of ant…
Fano manifolds obtained by blowing up along curves with maximal Picard number
Toru Tsukioka
The Picard number of a Fano manifold X obtained by blowing up a curve in a smooth projective variety is known to be at most 5, in any dimension greater than or equal to 4. We show…
A remark on Fano 4-folds having (3,1)-type extremal contractions
Toru Tsukioka
Let X be the blow-up of a smooth projective 4-fold Y along a smooth curve C and let E be the exceptional divisor. Assume that X is a Fano manifold and has an elementary extremal co…
Classification of Fano manifolds containing a negative divisor isomorphic to projective space
Toru Tsukioka
We classify Fano manifolds X containing a divisor E isomorphic to projective space such that the normal bundle is strictly negative.
