Noncollision singularities in a planar two-center-two-body problem.

摘要

In this work, we study a model of simplified four-body problem called planar two-center-two-body problem. In the plane, we have two fixed centers Q1 = (-x,0), Q 2 = (0, 0) of masses 1, and two moving bodies Q 3 and Q 4 of masses μ [special characters omitted]&
