| Outline of Final Research Achievements |
Critical phenomena with critical exponents, which measure the degree of divergences, are know to be universal. In two dimensions, some are obtained exactly but 3 dimensional Ising case, it is not obtained exactly. Recently conformal bootstrap method is proposed, and it provides very accurate numerical values of the critical exponents for 3 dimensional Ising model. We applied this method to polymer case, and found rather good values, The determinant method also can be applied, and we investigated the supersymmetric cases by this bootstrap method.

| Academic Significance and Societal Importance of the Research Achievements |
臨界指数を正確に求めることは、ゆらぎの物理現象を正しく理解することに繋がり、実験を説明できる理論を構築する上で重要なことである.得られた結果は共形場ブートストラップ法が有効であることを示し、今後の理論の重要な方向を示すものである.
