标题： Cosmological Quantum String Vacua and String-String Duality

摘要： 讨论了弦-弦对偶性对宇宙弦真空的影响。经典弦理论的宇宙真空由尺度因子T对偶性相互映射的不相交类别组成。然而，每个类别都受到初始/最终宇宙奇点的困扰。有人认为量子弦理论和弦-弦对偶性极大地解决了这些宇宙奇点问题，从而使不相交的经典宇宙真空以统一的方式连续连接起来。由此自然产生了膨胀宇宙学。 显示英文摘要

摘要： Implications of string-string dualities to cosmological string vacua are discussed. Cosmological vacua of classical string theories comprise of disjoint classses mapped one another by scale-factor T-duality. Each classes are, however, afflicted with initial/final cosmological singularities. It is argued that quantum string theories and string-string dualities dramatically resolve these cosmological singularities out so that disjoint classical cosmological vacua are continuously connected in a unified manner. A natural inflationary cosmology follows from this.
