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

arXiv, 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).

On some interpretation of linear frames in projective differential geometry

Дифференциальная геометрия многообразий фигур, 2018
The centroprojective group, i. e. the stabilizer G of a fixed point A in the group GP(n) of projective transformations of n-dimensional projective space Pn (n > 1) is considered in the paper. Two faithful representations of the linear quotient group of G

Flat-Parallel Minkowski Space and β-Change with α,β-Metric

Journal of Mathematics
The purpose of this paper is to examine the condition for a Finsler space with a generalized α,β-metric to be projectively flat. In addition, we establish that the Finsler space with generalized α,β-metric is a flat-parallel Minkowski space and derive ...

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

arXiv
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 ...

Integrating the Projective Transform with Particle Filtering for Visual Tracking

EURASIP Journal on Image and Video Processing, 2011
This paper presents the projective particle filter, a Bayesian filtering technique integrating the projective transform, which describes the distortion of vehicle trajectories on the camera plane.

Characterizing Geometric Designs [PDF]

Rendiconti di Matematica e delle Sue Applicazioni, 2010
We conjecture that the classical geometric 2-designs PGd(n, q), where 2 ≤ d ≤ n − 1, are characterized among all designs with the same parameters as those having line size q + 1.
