| Research Abstract |
Dynamical symmetry breaking in the gauge theory and its contribution to the space-time structure have been investigated under extreme circumstance, i.e.high temperature, high density, strong curvature and compact space-time. I have pointed out the usefulness of the dimensional regularization for an effective theory and found phenomena with a large regularization dependences. It gives us some predictions to judge the suitable circumstance to apply the effective theory.
