摘要：

Several theorems are proved relating the growth of spacetime curvature near a cosmic string to its ability to bend on length scales large compared with its diameter. In particular it is shown that the formation of closed loops with smaller than cosmological dimensions is incompatible with the approximation in which all the curvature of the string is confined to its core, with light deflections being given simply by the deficit angle.
