| Abstract: |
In this talk, I present a new exact solution to the equations of motion of Witten's open bosonic string field theory. The solution is constructed using boundary condition changing operators on the open string worldsheet, and depending on the choice of these operators, the solution can describe any time-independent configuration of D-branes. The solution also provides a field redefinition which relates string field theories constructed on different D-brane systems, thus providing a proof of background independence in string theory, at least in the open string sector. |
