10维空间中新的de Sitter解与Orientifold奇性

New de Sitter Solutions in Ten Dimensions and Orientifold Singularities

Clay Cordova, G. Bruno De Luca, Alessandro Tomasiello

摘要:

在以前的工作中,我们找到了具有dS $_4$因子和O~8-平面的超引力运动方程的十维解。我们推广这种分析,并获得其他解决方案,在同样的精神,与O8 $_+$和O6 $_-$。我们研究我们原来的解决方案更详细,特别是专注于O8 $_-$奇点和边界条件所产生的问题。我们还指出了一些以前已知的超对称AdS解决方案具有相同的本地行为在其O8 $_-$奇异性。

英文摘要:

In previous work, we found ten-dimensional solutions to the supergravity equations of motion with a dS$_4$ factor and O8-planes. We generalize this analysis and obtain other solutions in the same spirit, with an O8$_+$ and an O6$_-$. We examine our original solutions in more detail, focusing in particular on the O8$_-$ singularities and on the issues created by their boundary conditions. We also point out some previously known supersymmetric AdS solutions with the same local behavior at their O8$_-$ singularity.
