摘要:
We consider classical string spectrum of R-t x CP3, and construct a family of solutions with residual SU(2) symmetry by the dressing method on SU(4)/ U(3) sigma model. All of them obey the square-root type dispersion relation often found in the theory with su(2 vertical bar 2) symmetry. A single dyonic giant magnon is not found in this approach.
