Closed loop of classical string

  1. Aug 10, 2010 #1
    Has anyone seen a treatment of how to use the wave equation to describe a closed loop of string. Im talking ordinary strings here not the fancy string theory kind.

    I think its the same as a linear string, except with cyclical boundary conditions?

    Actually, there is a good treatment of this in Zwiebach's string theory book. Just check out the earlier chapters, and forget about trying to quantize the string.

    Basically, you take the wave equation for a non-closed string, and give it periodic boundary conditions, that's all.
