The Orthogonality Principle for Osserman Manifolds
Vladica Andrejić, Katarina Lukić
We introduce a new potential characterization of Osserman algebraic curvature tensors. An algebraic curvature tensor is Jacobi-orthogonal if hol…

On the existence of a curvature tensor for given Jacobi operators
Vladica Andrejić, Katarina Lukić
It is well known that the Jacobi operators completely determine the curvature tensor. The question of existence of a curvature tensor for given Jacobi operators naturally arises, w…
