KEK素粒子原子核研究所・理論セミナー（大川 祐司 氏） - KEK｜高エネルギー加速器研究機構概要 In typical examples of the AdS/CFT correspondence, the world-sheet theory with holes in the presence of D-branes is assumed to be equivalent in a low-energy limit to a world-sheet theory without holes for a different background such as AdS₅ × S⁵. In the case of the bosonic string, we claim under the assumption of this equivalence that open string field theory on N coincident D-branes can be use
