Summary: The restricted (equilateral) four-body problem consists of three bodies of masses \(m_1\), \(m_2\) and \(m_3\) (called primaries) lying in a Lagrangian configuration of the three-body problem, i.e. they remain fixed at the apices of an equilateral triangle in a rotating coordinate system. A massless fourth body moves under the Newtonian gravitation law due to the three primaries; as in the restricted three-body problem the fourth mass does not affect the motion of the three primaries. In this paper we show a global regularization of binary collisions of the infinitesimal body with two of the primaries.For the entire collection see [Zbl 1290.00026].
