We study a second-order parallel symmetric tensor in an 𝒮-manifold and show that there is no semiparallel hypersurface in the 𝒮-space forms M ˜ 2 n + s c $$ {\tilde{M}}^{2n+s}(c) $$ with c ≠ s.

𝒮-空间形式的𝒮-流形和半平行超曲面上的二阶平行张量

我们研究了 𝒮 流形中的二阶平行对称张量,并表明在 𝒮 空间形式 M ~ 2 n + sc $$ {\tilde{M}}^{2n+s}( c) $$ 且 c ≠ s。
