| ABSTRACT: |
The emergence of integrability on both sides of the AdS/CFT correspondence has continued to provide improvements in our understanding of the large-N gauge theory and string theory. In light of the integrability, the correspondence between classical spinning string solutions and the dual spin-chain states has been studied extensively. In particular, on the string side, I will concentrate on string solutions which are related to kink soliton solutions of Complex sine-Gordon equation via the so-called Pohlmeyer's reduction procedure. Such string states can be shown to be dual to BPS boundstates of many magnons in the spin-chain description of planar N = 4 SUSY Yang-Mills theory. Ref. hep-th/0605155, 0608047, 0609026, 0610295.
