On affine hypersurfaces with Parallel Cubic Form Relative to affineα-connection
收藏 引用
Acta Mathematica Sinica,English Series 2024年 第4期40卷 1099-1114页
作者: Ce Ce LI Cheng XING Hui Yang XU School of Mathematics and Statistics He’nan University of Science and TechnologyLuoyang 471023P.R.China School of Mathematical Sciences and LPMC Nankai UniversityTianjin 300071P.R.China
Similar to Nomizu-Pinkall's geometric characterization of the Cayley surface and Hu-Li-Zhang's characterization of the Cayley hypersurface,how can one characterize the generalized Cayley hypersurfaces?In this paper,by... 详细信息

Acta Mathematica Scientia 2023年 第6期43卷 2413-2429页
作者: 徐辉阳 李策策 School of Mathematics and Statistics Henan University of Science and TechnologyLuoyang 471023China
In this paper,we study locally strongly convex affine hypersurfaces with the vanishing Weyl curvature tensor and semi-parallel cubic form relative to the Levi-Civita connection of the affine metric.As a main result,we... 详细信息
