标题： Nonperturbative Effects in Noncritical Strings with Soliton Backgrounds

摘要： 我们显式构造了$D<2$(或$c<1$) 弦理论中的孤子算子，并表明施温格-戴森方程允许以这些孤子作为背景的解。 在弱耦合极限下，1-孤子背景的主要贡献被显式计算，并显示与弦方程的非微扰分析一致。 我们建议应将费米子视为基本的动力学变量，因为宏观环和孤子都是以它们的双线性形式构造的。 显示英文摘要

摘要： We explicitly construct soliton operators in $D<2$ (or $c<1$) string theory, and show that the Schwinger-Dyson equations allow solutions with these solitons as backgrounds. The dominant contributions from 1-soliton background are explicitly evaluated in the weak coupling limit, and shown to agree with the nonperturbative analysis of string equations. We suggest that fermions should be treated as fundamental dynamical variables since both macroscopic loops and solitons are constructed in their bilinear forms.
