dc.description.abstract | Since Maldacena's conjecture for the AdS/CFT duality has been introduced, there have been various attempts to verify the AdS/CFT duality. However, we have a problem to show the AdS/CFT duality because string theory and conformal field theory are described in the different range of λ. To solve this problem, scientists have made an effort to find solutions all λ in the conformal field theory side by S-matrix and Bethe ansatz equation. In this thesis, we discuss AdS/CFT duality on AdS_(5)×S^(5), starting with basic concept of string theory and conformal field theory. We examine carefully what is he difficulties to test AdS/CFT duality. We also review classical string theory on AdS_(5)×S^(5) and spin chain of N=4 super Yang-Mill Theory. Mainly we discuss about S-matrix of elementary magnon state and magnon bound state with Bethe ansatz equation and dispersion relation to show AdS/CFT duality.;끈이론과 등각장론이 일치한다는 게이지/중력 이중성에 대한 말다세나의 추측(Maldacena’s Conjecture) 이후, 게이지/중력 이중성을 증명하기 위한 많은 시도가 있었다. 그러나 다른 λ범위에서 기술되는 끈이론과 등각장론 때문에 게이지/중력 이중성을 증명하는 것에는 문제가 있다. 이 문제를 해결하기 위해 등각장론 분야에서 산란행렬(S-matrix)와 베테안사츠 방정식(Bethe ansatz equation)을 이용하여 모든λ에 대한 답을 찾기 위해 노력해왔다. 우리는 이 논문에서 AdS_(5)×S^(5)공간 위에서의 게이지/중력이중성에 대해 토론한다. 우선 끈이론과 등각장론의 기본개념 설명을 하고 게이지/중력 이중성을 증명할 때 생기는 어려움이 무엇인지 진단할 것이다. 또한 AdS_(5)×S^(5) 공간 위에서의 고전 끈이론과 N=4 슈퍼 양-밀 이론(Super Yang-Mill)을 복습한다. 게이지/중력 이중성을 보이기 위해 기본 마그논 상태(elementary magnon state)와 속박 마그논 상태(magnon bound state)에 대한 산란행렬을 베테안사츠 방정식과 분산관계(dispersion relation)와 함께 토론한다. | - |
