Cosmological gravitomagnetism and Mach's principle
, 2006 The spin axes of gyroscopes experimentally define local non-rotating frames. But what physical cause governs the time-evolution of gyroscope axes? We consider linear perturbations of Friedmann-Robertson-Walker cosmologies with k=0.

Gyroscope precession in cylindrically symmetric spacetimes [PDF]
, 2000 We present calculations of gyroscope precession in spacetimes described by Levi-Civita and Lewis metrics, under different circumstances. By doing so we are able to establish a link between the parameters of the metrics and observable quantities ...

Gyroscope deviation from geodesic motion: quasiresonant oscillations on a circular orbit [PDF]
, 2003 General relativistic spin-orbit interaction leads to the quasiresonant oscillation of the gyroscope mass center along the orbital normal. The beating amplitude does not include the speed of light and equals the ratio of the intrinsic momentum of the ...
