Aberration by gravitational lenses in motion
Simonetta Frittelli
It is known that a fully relativistic integration of the null geodesics of a weak perturbation of flat spacetime leads to a correction of order to the bending angle and time…

Einstein boundary conditions in relation to constraint propagation for the initial-boundary value problem of the Einstein equations
Simonetta Frittelli, Roberto Gomez
We show how the use of the normal projection of the Einstein tensor as a set of boundary conditions relates to the propagation of the constraints, for two representations of the Ei…

Einstein boundary conditions for the 3+1 Einstein equations
Simonetta Frittelli, Roberto Gomez
In the 3+1 framework of the Einstein equations for the case of vanishing shift vector and arbitrary lapse, we calculate explicitly the four boundary equations arising from the vani…
