Some Issues in Non-commutative Tachyon Condensation

Abstract

Techniques of non-commutative field theories have proven to be useful in describing D-branes as tachyonic solitons in open string theory. However, this procedure also leads to unwanted degeneracy of solutions not present in the spectrum of D-branes in string theories. In this paper we explore the possibility that this apparent multiplicity of solutions is due to the wrong choice of variables in describing the solutions, and that with the correct choice of variables the unwanted degeneracy disappears.
