Classification of sextic curves in the Fano 3-fold with rational Galois covers in

Quo-Shin Chi, Zhenxiao Xie, Yan Xu

In this paper, we classify sextic curves in the Fano -fold (the smooth quintic del Pezzo -fold) that admit rational Galois covers in the complex ${\mathbb…

Fano 3-folds and classification of constantly curved holomorphic -spheres of degree in the complex Grassmannian

Quo-Shin Chi, Zhenxiao Xie, Yan Xu

Up to now the only known constantly curved sextic curve, i.e., holomorphic 2-sphere of degree 6, in the complex has been the first associated curve of the Veronese curve o…

The Isoparametric Story, a Heritage of Élie Cartan

Quo-Shin Chi

In this article, we survey along the historical route the classification of isoparametric hypersurfaces in the sphere, paying attention to the employed techniques in the case of fo…

Structure of minimal 2-spheres of constant curvature in the complex hyperquadric

Quo-Shin Chi, Zhenxiao Xie, Yan Xu

In this paper, the singular-value decomposition theory of complex matrices is explored to study constantly curved 2-spheres minimal in both and the hyperquadric of…

Isoparametric hypersurfaces with four principal curvatures, IV

Quo-Shin Chi

We prove that an isoparametric hypersurface with four principal curvatures and multiplicity pair is either the one constructed by Ozeki and Takeuchi, or one of the two cons…
