A necessary condition for brane solutions to have their origins in string field theory

TL;DR

This paper establishes a necessary condition for brane solutions to originate from string field theory, focusing on T-duality properties and restrictions on S-brane distributions.

Contribution

It introduces a specific condition that distinguishes which brane solutions can be derived from string field theory based on T-duality compatibility.

Findings

T-duality must be well-defined for solutions to originate from string field theory

Not all S-brane solutions satisfy the T-duality condition

Certain S-brane distributions are forbidden under the derived condition

Abstract

We present a necessary condition for brane solutions to have their origins in string field theory. For such solutions, T-duality operations between IIA and IIB solutions should be well-defined. Nevertheless, not all S-brane solutions have T-duality. The solutions that have T-duality and may accordingly be regarded as low-energy solutions of string field theory satisfy a condition in which some S-brane distributions are forbidden.
