我们在IIA弦理论中发现了一类新的AdS{sub4}真空族。内部空间在拓扑上是复射影空间Cp{sup 3}或‘’旗形‘’SU(3)/(U(1)Xu(1)),但度量一般既不是爱因斯坦也不是Kaehler。所有已知的模都是由通量稳定的,不使用量子效应或取向平面。这种分析完全是十维的,不依赖于关于卡鲁扎-克莱因约化的假设。
We find a new family of AdS{sub 4} vacua in IIA string theory. The internal space is topologically either the complex projective space CP{sup 3} or the ''flag manifold'' SU(3)/(U(1)xU(1)), but the metric is in general neither Einstein nor Kaehler. All known moduli are stabilized by fluxes, without using quantum effects or orientifold planes. The analysis is completely ten-dimensional and does not rely on assumptions about Kaluza-Klein reduction.
