Constraints on string networks with junctions

E. J. Copeland, T. W. B. Kibble, D. A. Steer

We consider the constraints on string networks with junctions in which the strings may all be different, as may be found for example in a network of $(p, q)$ cosmic superstrings. We…

Collisions of strings with Y junctions

E. J. Copeland, T. W. B. Kibble, D. A. Steer

We study the dynamics of Nambu--Goto strings with junctions at which three strings meet. In particular, we exhibit one simple exact solution and examine the process of intercommuti…
