Outline of Final Research Achievements

We have investigated some physical properties of the identity-based classical solutions in bosonic and super string field theory, numerically and analytically.
Using Erler-Maccaferri's method, we have constructed new classical solutions in bosonic string field theory.
In the modified cubic open superstring field theory, we have proposed a new method for numerical calculations in the level truncation. In the WZW-like open superstring field theory, we have performed the component field expansion, up to the lowest level, including the fermion sector in the ten dimensional space-time.
