Research Abstract |
We studied nonperturbative lattice formulation of fermions in the gravitational field, anomalous gauge theories and low-dimensional supersymmetric gauge theories, on the basis of theoretical analyses and numerical simulations. As the most significant achievement, we confirmed in a lattice formulation of the two-dimensional N=(2,2) supersymmetric Yang-Mills theory that supersymmetry (which is broken by the lattice regularization) is restored in the continuum limit, by numerically measuring supersymmetric Ward-Takahashi identities.
