Curvature properties of some class of hypersurfaces in Euclidean spacesKatarzyna SawiczDepartment of Applied Mathematics, Karol Adamiecki University of Economics in Katowice, Katowice, PolandAbstract: We determine curvature properties of pseudosymmetry type of hypersurfaces in Euclidean spaces $\mathbb E^{n+1}$, $n\geqslant 5$, having three distinct non-zero principal curvatures $\lambda_1$, $\lambda_2$ and $\lambda_3$ of multiplicity $1$, $p$ and $n-p-1$, respectively. For some hypersurfaces having this property the sum of $\lambda_1$, $\lambda_2$ and $\lambda_3$ is equal to the trace of the shape operator of $M$. We present an example of such hypersurface. Keywords: Tachibana tensor; pseudosymmetry type curvature condition; hypersurface; principal curvature Classification (MSC2000): 53B20; 53B25; 53C25 Full text of the article: (for faster download, first choose a mirror)
