Outline of Final Research Achievements

Recent study on superstring theory has made it clear that supersymmetric gauge theories are key to approach to problems of early universe and quantum gravity. We have thus carried out our research in order to establish a way to study the supersymmetric gauge theories numerically.
As a result, we specified that the so called Sugino model is the most useful algorithm to simulate the supersymmetric gauge theories. The original Sugion model has an undesirable property that there exists many degenerated unphysical vacua. We solved this problem in an elegant way and established a foundation to study supersymmetric gauge theories in numerical way.
