Variétés horosphériques de Fano
, 2008 International audienceA horospherical variety is a normal algebraic variety where a reductive algebraic group acts with an open orbit which is a torus bundle over a flag variety. For example, toric varieties and flag varieties are horospherical.

Birationally solid Fano 3-fold hypersurfaces
, 2023 A Fano variety of Picard number $1$ is said to be \textit{birationally solid} if it is not birational to a Mori fiber space over a positive dimensional base.

Covered by lines and Conic connected varieties
Le Matematiche, 2011 We study some properties of an embedded variety covered by lines and give a numerical criterion ensuring the existence of a singular conic through two of its general points. We show that our criterion is sharp.

, 2006 A horospherical variety is a normal algebraic variety where a reductive algebraic group acts with an open orbit which is a torus bundle over a flag variety. For example, toric varieties and flag varieties are horospherical. In this paper, we classify Fano horospherical varieties in terms of certain rational polytopes that generalize the reflexive ...

Plasmon-induced transparency effect of flexible terahertz metasurface
上海师范大学学报. 自然科学版In recent years, the terahertz micro/nano-photonics research group of Shanghai Normal University has carried out a series of research work on the terahertz (THz) plasmon-induced transparency (PIT) using planar metamaterials, which attract highly ...

On subvarieties of degenerations of Fano varieties
International Journal of MathematicsThe goal of this work is to study geometric properties of geometrically irreducible subschemes on degenerations of Fano varieties (more generally, of separably rationally connected varieties). It is known that these geometrically irreducible subschemes exist when the ground field has characteristic zero or contains an algebraically closed subfield. We

Deformations of Q-Fano 3-folds and weak Fano manifolds [PDF]
Fano varieties are one of important classes in the classi cation of algebraic varieties. In this thesis, we mainly study problems on deformations of Fano varieties motivated by the classi cation problems.
