Title: Collisions of superconducting strings with Y-junctions
Abstract: 
In this talk, I will discuss the dynamics of Nambu-Goto and superconducting strings 
with Y-junction at which three strings meet. When the two strings collide, they may
be linked by a third string with different tension (and current), instead of intercommutation. 
In particular, I show the kinematical constraints on this process and the requirement to 
form the Y-junction when two strings collide.
