Classification of embedded projective manifolds swept out by rational homogeneous varieties of codimension one
Kiwamu Watanabe
We give a classification of embedded smooth projective varieties swept out by rational homogeneous varieties whose Picard number and codimension are one.

Lengths of chains of minimal rational curves on Fano manifolds
Kiwamu Watanabe
In this paper, we consider a natural question how many minimal rational curves are needed to join two general points on a Fano manifold X of Picard number 1. In particular, we stud…

A bound of lengths of chains of minimal rational curves on Fano manifolds of Picard number 1
Kiwamu Watanabe
In this paper, we investigate the minimal length of chains of minimal rational curves needed to join two general points on a Fano manifold of Picard number 1. In particular, we giv…
