Contribution
It introduces a novel mapping between vacuum string field theory projectors and GMS solitons, linking geometric conditions to commutative modes and discussing implications for closed string states.
Findings
D-brane projectors correspond to GMS solitons via the new map
Singular geometry conditions relate to commutative modes
Discussion on candidate closed string states and wedge states
Abstract
In this paper we map the D-brane projector states in the vacuum string field theory to the noncommutative GMS solitons based on the recently proposed map of Witten's star to Moyal's star. We find that the singular geometry conditions of Moore and Taylor are associated with the commutative modes of these projector states in our framework. The properties of the candidate closed string state and the wedge state are also discussed, and the possibility of the non-GMS soliton in VSFT is commented.
