Delays in Open String Field Theory

Understand

We study the dynamics of light-like tachyon condensation in a linear dilaton background using level-truncated open string field theory.

• The equations of motion are found to be delay differential equations.
• This observation allows us to employ well-established mathematical methods that we briefly review.
• At level zero, the equation of motion is of the so-called retarded type and a solution can be found very efficiently, even in the far light-cone future.
