Research Abstract

リー環A^<(1)>_<n-1>の対称性を持つ1次元スピン鎖の相関関数の積分表示を、領域|q|=1でもとめた。相関関数の満たすべき差分方程式の解をtype-IのVertex Opetarorsのボゾン表示をもとめることにより構成した。
次に19Vertex Modelの相関関数を、領域|q|=1でもとめた。相関関数の満たすべき差分方程式の解をtype-IのVertex Opetarorsのより具体的な表示を、ボゾン、フェルミオンによりもとめることにより導いた。
次にXXZ chain with a boundaryの相関関数を領域|q|=1でもとめた。相関関数の満たすべき差分方程式の解を構成した。より具体的方法はBoundary Statesのボゾン表示をもとめることによった。Lukyanovのuv-cutoffによらずに、直接的なVertex Operatorsのボゾン表示をもちいて、uv-cutoff的ではない直接的なBoundary Stateを構成した。
次に有限サイズかつ両開境界条件のXXZ模型の固有ベクトルをもとめた。方法は擬Boundary Statesのボゾン表示をもとめることによった。
次にSU(n)不変massive Thirring模型の形状因子をもとめた。方法はBoundary Statesのボゾン表示をもとめることによった。Local Operatorsのボゾン表示には、年度の最初に行ったA^<(1)>_<n-1>、鎖の研究が役にたった。
