摘要：The elliptic loop equation of a cosmic string is studied in Minkowski space and during the radiation-dominated era in the Robertson-Walker universe. If the loops expand with Hubble flow at the time of formation of loops, and when the major semi-axis is longer than the minor semi-axis by several Schwarzschild radii, it should not collapse to form a black hole.
