| アブストラクト: |
I give a review on recent development of analytic classical solutions of the cubic string field theory (CSFT). Because of the gauge invariance of CSFT, the moduli space of the solutions has a rich structure. Nontrivial solutions are candidate for the closed string vacuum which is expected for the tachyon condensation in unstable D-brane dynamics. Evidences for this conjecture are given in several ways --- analysis of cohomology, level truncation and gauge invariance. |
