Abstract
摘摘要
|
Traditionally, there was no systematical approach to include the classical "stringy" effects in the non-perturbative studies. Therefore, the string effective theories basically do not distinguish themselves from the pointlike particle model, and suffer some long-standing problems. In this talk, I will show that the recent progress on the classification of $\alpha'$ corrections provides resolutions for challenges such as dS/AdS vacua, big-bang singularity etc.
