Fano manifolds which are not slope stable along curves [PDF]

open access: yesarXiv, 2011
We show that a Fano manifold (X,-K_X) is not slope stable with respect to a smooth curve Z if and only if (X,Z) is isomorphic to one of (projective space, line), (product of projective line and projective space, fiber of second projection) or (blow up of projective space along linear subspace of codimension two, nontrivial fiber of blow up).

Embedding dual nets in affine and projective spaces [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 1994
This article determines the structure of arbitrary nets (finite or infinite) whose duals may be embedded into affine or projective space. The main results are that nets whose duals may be embedded into projective space are pseudo-regulus nets and nets ...

Petty projection inequality on the sphere and on the hyperbolic space [PDF]

open access: yesarXiv
Using gnomonic projection and Poincar\'e model, we first define the spherical projection body and hyperbolic projection body in spherical space $\mathbb{S}^n$ and hyperbolic space $\mathbb{H}^n$, then define the spherical Steiner symmetrization and hyperbolic Steiner symmetrization, finally prove the spherical projection inequality and hyperbolic ...
