作为扩散系统的弦论
String theory as a diffusing system
摘要:
开弦场论(OSFT)快子模有效非定域动力学的最新结果表明,可以构造出服从扩散方程的近似解。我们认为,这种结构是继承了完整的理论,它承认一个普遍的配方。事实上,所有已知的精确OSFT解都是扩散表面态的叠加。特别地,扩散方程是OSFT规范对称性的时空表现。
英文摘要:
Recent results on the effective non-local dynamics of the tachyon mode of open string field theory (OSFT) show that approximate solutions can be constructed which obey the diffusion equation. We argue that this structure is inherited from the full theory, where it admits a universal formulation. In fact, all known exact OSFT solutions are superpositions of diffusing surface states. In particular, the diffusion equation is a spacetime manifestation of OSFT gauge symmetries.
