%0 Journal Article %T Real hypersurfaces in complex two-plane Grassmannians with commuting restricted Jacobi operators %A Eunmi Pak %A Young Jin Suh %A Changhwa Woo %J Mathematics %D 2014 %I arXiv %X In this paper, we have considered a new commuting condition, that is, $(R_\xi\phi) S = S (R_\xi\phi)$ \big(resp. $(\Bar{R}_N\phi) S = S (\Bar{R}_N\phi$)\big) between the restricted Jacobi operator~$R_\xi\phi$ (resp. $\Bar{R}_N\phi$), and the Ricci tensor $S$ for real hypersurfaces $M$ in $G_2({\mathbb C}^{m+2})$. In terms of this condition we give a complete classification for Hopf hypersurfaces $M$ in $G_2({\mathbb C}^{m+2})$. %U http://arxiv.org/abs/1409.7177v1
