Rotational locks for gravity gradient satellites
… of periods 2π and 4 π are found and their variational stability investigated by Floquet analysis. The results which are presented on stability charts show that for satellites that deviate appreciably from axial symmetry, the stable periodic solutions occur at eccentricities which tend to …

Stability of Einstein Manifolds
… we find curvature conditions which ensure the stability of Einstein manifolds with respect to the Einstein-Hilbert functional, i.e. that the second variation of the Einstein-Hilbert functional at the metric is nonpositive in the direction of transverse-traceless tensors. The second part of the …
