论文摘要
我们发现并研究了17个新的DE Sitter解决方案，具有十维（10D）IIB型超重力，以及相交的D5-BRANES和ERINCIFOLD O5-PLANES，以及新的Minkowski One。这些溶液是在6D组歧管上以数值获得的，其紧凑性是为其中4个建立的。我们证明，使用有限的四个标量磁场的有效理论，我们所有的DE Sitter解决方案都是扰动的不稳定。我们最终分析了我们的解决方案是否可以晋升为经典的字符串背景。他们中的一些人看起来像是良好的候选人，因为他们满足到目前为止所施加的所有要求。
We find and study 17 new de Sitter solutions of ten-dimensional (10d) type IIB supergravity with intersecting D5-branes and orientifold O5-planes, as well as a new Minkowski one. These solutions are obtained numerically on 6d group manifolds, the compactness of which is established for 4 of them. We show that all our de Sitter solutions are perturbatively unstable, using a restricted 4d effective theory of four scalar fields. We finally analyse whether our solutions can be promoted to classical string backgrounds. Several of them appear as good candidates, as they satisfy all requirements imposed so far.
