Osserman and conformally Osserman manifolds with warped and twisted product structure
M. Brozos-Vazquez, E. Garcia-Rio, R. Vazquez-Lorenzo
We characterize Osserman and conformally Osserman Riemannian manifolds with the local structure of a warped product. By means of this approach we analyze the twisted product struct…
Four-dimensional Osserman metrics of neutral signature
E. Garcia-Rio, P. Gilkey, M. E. Vazquez-Abal +1
In the algebraic context, we show that null Osserman, spacelike Osserman, and timelike Osserman are equivalent conditions for a model of signature (2,2). We also classify the null…
Stanilov-Tsankov-Videv Theory
M. Brozos-Vazquez, B. Fiedler, E. Garcia-Rio +6
We survey some recent results concerning Stanilov-Tsankov-Videv theory, conformal Osserman geometry, and Walker geometry which relate algebraic properties of the curvature operator…
