论文摘要
时间样线性dilaton背景允许一种经典的解决方案，该解决方案描述了在瞬间创建的封闭折叠字符串。我们将这些字符串称为即时折叠字符串（IFS）。我们研究了一个IF的确切世界表CFT描述，该描述涉及两个顶点操作员，这些顶点操作员描述了两个开放式弦模式，它们在类似时间的FZZT-Brane上传播，该模式在IFS上扮演了调节器的作用。我们利用此描述来计算与IFSS相关的最基本数量 - 其生产率。简要讨论了该计算对弦宇宇宙学和黑洞内部的一些含义。
Time-like linear dilaton backgrounds admit a classical solution that describes a closed folded string that is created at an instant. We refer to such strings as Instant Folded Strings (IFS). We study an exact worldsheet CFT description of an IFS that involves two vertex operators which describe two open string modes that propagate on a time-like FZZT-brane, which plays the role of a regulator to the IFS. We take advantage of this description to calculate the most basic quantity associated with IFSs - their production rate. Some implications of this calculation to stringy cosmology and black hole interior are briefly discussed.
