论文摘要
我们介绍了与对局部超级重力的通量减少中局部(非相互作用)O6平面相反的超级强烈解决方案的明确例子,并针对这种解决方案的存在提出了一些批评。我们详细验证了涂抹后的Erientifold溶液如何在大容量/弱耦合极限(如预期)中成为局部溶液的良好近似值。我们还找到了一个异国情调的解决方案,在反应之前,内部空间具有边界,当包括反应时,边界消失了,空间关闭。然而,异国情调的例子在各处的超级近似之外。
We present explicit examples of supergravity solutions corresponding to backreacting localised (non-intersecting) O6 planes in flux reductions of massive IIA supergravity and address some criticism towards the very existence of such solutions. We verify in detail how the smeared orientifold solution becomes a good approximation to the localised solution in the large volume/weak coupling limit, as expected. We also find an exotic solution where prior to backreaction the internal space has a boundary and when backreaction is included the boundary disappears and the space closes off. The exotic example is however outside of the supergravity approximation everywhere.
