我们认为弦理论中的真空在弱耦合时渐近于线性声子背景，它是全息的。在这样的真空中，完整的弦理论与在更少维度中没有引力的理论是“对偶的”。对偶理论一般不是局域量子场论。弦真空的激发，可以在弱耦合区域用世界片方法研究，在对偶理论中产生可观测量。一个有趣的例子是在平行NS 5-膜的近视界背景下的弦理论，CHS模型，它是解耦NS 5-膜理论（“小弦理论”）的对偶。这种对偶性可以用来研究这个理论中的一些可观测量和它们的一些相关函数。另一个有趣的例子是“旧”矩阵模型，它给出了二维弦理论的全息描述。
We argue that vacua of string theory which asymptote at weak coupling to linear dilaton backgrounds are holographic. The full string theory in such vacua is ``dual'' to a theory without gravity in fewer dimensions. The dual theory is generically not a local quantum field theory. Excitations of the string vacuum, which can be studied in the weak coupling region using worldsheet methods, give rise to observables in the dual theory. An interesting example is string theory in the near-horizon background of parallel NS5-branes, the CHS model, which is dual to the decoupled NS5-brane theory (``little string theory''). This duality can be used to study some of the observables in this theory and some of their correlation functions. Another interesting example is the ``old'' matrix model, which gives a holographic description of two dimensional string theory.
