| Research Abstract |
In the academic year of 2000, I continued to study the open-string/D-brane system in the presence of B field with B. Chen, T. Matsuo and K. Murakami and revealed several interesting properties which include the profiles of noncommutative solitons. In 2001 academic year, I mainly studied the boundary string field theory (BSFT) and its extension, having in mind that it can be viewed as an application of boundary integrable system. I discussed the relationship of the action of BSFT with g function and the construction of the off-shell boundary and crosscap states. In the last six months, I collaborated with Shin Nakamura (KEK) to extend the BSFT to the case in which the RP^2 geometry is included.
