We analyze the geodesic motion in Schwarzschild spacetime with the weak-field limit. We investigate all geodesic types of the test particle by solving the geodesic equation and analyzing the behavior of effective pote...
We consider geodesic motion in a particular Kundt type-Ⅲ spacetime in which the Einstein–Yang–Mills equations admit the solutions.On a particular surface as constraint,we project the geodesics into the(x,y)plane an...

Numerical method is applied to the investigation of the GAM damping rate with the finite k effects included. It is found that generally the damping rate given by the analytical method is smaller than that given by the...

By means of the orthonormal frame,the motion of the axis of a gyroscope freely falling along the radial geodesic in the space-time of a black hole with a global monopole is investigated.It is shown that the axis of th...
