论文摘要
根据ADS $ _5 \ times $ s $^5 $背景中1/2-BPS D-BRANES的协变式超弦描述，有两种纯粹的Instantonic D-Branes。一个是众所周知的d（-1） - brane或d-instanton，另一个是d1-brane，跨越了s $^5 $内部的二维子空间。我们确定实际的1/2-BPS激发型D1-Brane构型及其超对称结构。从结果得出的结论是，任何半径等于S $^5 $的球形D1-Instanton是1/2 bps。在评估了1/2-BPS D1-Instanton动作后，我们讨论了D1-Instanton与$（P，Q）$ String Instanton的关系。我们还讨论了可能的1/2-BP和1/4-BPS多个D1-Instanton配置。
According to the covariant open superstring description of 1/2-BPS D-branes in the AdS$_5\times$S$^5$ background, there are two kinds of purely instantonic D-branes. One is the well known D(-1)-brane or D-instanton, and another is the D1-brane spanning a two dimensional subspace inside S$^5$. We identify the actual 1/2-BPS instantonic D1-brane configurations and their supersymmetry structures. From the results, it is concluded that any spherical D1-instanton with the radius equal to that of S$^5$ is 1/2-BPS. After evaluating the 1/2-BPS D1-instanton action, we discuss the relation of D1-instanton with the $(p, q)$ string instanton. We also discuss the possible 1/2-BPS and 1/4-BPS multiple D1-instanton configurations.
