Abstract. In differential geometry several differential equation systems are known which allow the determination of the Riemannian metric from the curvature tensor in normal coordinates. We consider...
Stanilov-Tsankov-Videv Theory (2007)
Brozos-Vazquez, M., Fiedler, B., Garcia-Rio, E., Gilkey, P., Nikcevic, S., Stanilov, G., ...
We survey some recent results concerning Stanilov-Tsankov-Videv theory, conformal Osserman geometry, and Walker geometry which relate algebraic properties of the curvature operator to the underlying...

Refuting the odd number limitation of time-delayed feedback control (2006)
Fiedler, B., Flunkert, V., Georgi, M., Hoevel, P., Schoell, E.
We refute an often invoked theorem which claims that a periodic orbit with an odd number of real Floquet multipliers greater than unity can never be stabilized by time-delayed feedback control in the...

The structure of algebraic covariant derivative curvature tensors (2004)
Diaz-Ramos, J., Fiedler, B., Garcia-Rio, E., Gilkey, P.
We use the Nash embedding theorem to construct generators for the space of algebraic covariant derivative curvature tensors.
Generators of algebraic covariant derivative curvature tensors and Young symmetrizers (2003)
We show that the space of algebraic covariant derivative curvature tensors R' is generated by Young symmetrized tensor products W*U or U*W, where W and U are covariant tensors of order 2 and 3 whose...
On the symmetry classes of the first covariant derivatives of tensor fields (2003)
We show that the symmetry classes of torsion-free covariant derivatives $\nabla T$ of r-times covariant tensor fields T can be characterized by Littlewood-Richardson products $\sigma [1]$ where...
Fahrig, R., Nickel, B., Wilfert, F., Leisser, C., Krupitza, G., ...
Induced chemoresistance leads to the reduction of apoptotic responses. Although several drugs are in development that circumvent or decrease existing chemoresistance, none has the potential to...
Determination of the structure of algebraic curvature tensors by means of Young symmetrizers (2002)
For a positive definite fundamental tensor all known examples of Osserman algebraic curvature tensors have a typical structure. They can be produced from a metric tensor and a finite set of...
Ideal decompositions and computation of tensor normal forms (2002)
Symmetry properties of r-times covariant tensors T can be described by certain linear subspaces W of the group ring K[S_r] of a symmetric group S_r. If for a class of tensors T such a W is known, the...

We exhibit pseudo Riemannian manifolds which are Szab\'o nilpotent of arbitrary order, or which are Osserman nilpotent of arbitrary order, or which are Ivanov-Petrova nilpotent of order 3.
Magnetic and collective rotation in Br-79 (2002)
