A detailed study of the relativistic problem of three bodies was presented
by Brumberg ([1,2]). He derived the equations of motion for the general pro
blem and he also deduced the corresponding equations for the restricted one
. The existence and linear stability of triangular equilibrium points of th
e restricted problem were studied by Bhatnagar and Hallan ([3]). In this co
ntribution we focus on the collinear libration points. We study the existen
ce, position and stability of these points.
