  1. Hidden Yangian symmetry in sigma model on squashed sphere 川口　維男（京大理） I.K. Kentaroh Yoshida, arXiv:1008.0776 I.K. Domenico Orlando, Kentaroh Yoshida, in preparation に基づく @理研 ’10/12/17

  2. 可積分性が重要 AdS/CFT対応の検証 可解スピン鎖模型 AdS5×S5上の type ⅡB super string 4次元N=4 super Yang-Mills 等価 symmetric coset 上のシグマ模型 古典可積分系 無限次元対称性 string backgroundになるものの分類 Zarembo ‘10

  3. non-symmetric cosetへの拡張 string backgroundになるsymmetric coset 全てAdS×(internal manifold)の形 一方で AdS/CFTの拡張 non symmetric coset上のシグマ模型 AdS/NRCFTなど 無限次元対称性の存在？ squashed S3上のシグマ模型が無限次元対称性を持つことを示した

  4. 本講演では ① symmetric cosetの際の無限次元対称性の構成法 squashed S3(warped AdS3)上のシグマ模型 における無限次元対称性の構成 ② ③ string backgroundへの格上げへ向けて
