3 Jan 2007 | Subject: | Differential Geometry | Abstract: | We consider four-dimensional Riemannian manifolds with commuting higher order Jacobi operators defined on two-dimensional orthogonal subspaces (polygons) and on their orthogonal subspaces. indent More precisely, we discuss higher order Jacobi operator $mathcal{J}(X)$ and its commuting associated operator $mathcal{J}(X^{perp})$ induced by the orthogonal complement $X^{perp}$ of the vector $X$, i. e. $mathcal{J}(X)circmathcal{J}(X^{perp})=mathcal{J}(X^{perp})circ mathcal{J}(X)$. indent At the end some new central theorems have been cited. The latter are due to P. Gilkey, E. Puffini and V. Videv, and have been recently obtained. | Source: | arXiv, math/0701090 | Services: | Forum | Review | PDF | Favorites |
