Consistent results with Boundary String Field Theory (BSFT)
Determined decay modes of D-Dbar systems on orbifolds
Extended the solution generating technique for broader applications
Abstract
We propose the relationships between the noncommutative solitons and the (fractional) D-branes on the C^2/Z_n orbifold and extend the solution generating technique for the orbifold. As applications, we determine how tachyon condensations occur in various D-Dbar systems on the orbifolds. The calculations give results consistent with BSFT. The extended solution generating technique enables us to calculate more general decay modes of D-Dbar systems.
