论文摘要
对称产品Orbifold $ \ text {sym} _n（\ Mathbb {t}^4）$的BPS相关因素是从双重世界表的理论中复制的通量。更具体地说，我们表明，可以将其升降到覆盖面的对称性Orbifold BPS状态的世界表二，从而使相关器的匹配基本上表现出来。我们还认为，使用世界表格上合适的DDF操作员，可以将该论点推广到任意后代。
The BPS correlators of the symmetric product orbifold $\text{Sym}_N(\mathbb{T}^4)$ are reproduced from the dual worldsheet theory describing strings on $\text{AdS}_3\times {\rm S}^3\times \mathbb{T}^4$ with minimal ($k=1$) NS-NS flux. More specifically, we show that the worldsheet duals of the symmetric orbifold BPS states can be identified with their lift to the covering surface, thereby making the matching of the correlators essentially manifest. We also argue that the argument can be generalised to arbitrary descendants, using suitable DDF operators on the worldsheet.
