我们进行了彻底的分析的模空间的级联规范理论上发现的p D3-膜和M包裹D5-膜在锥的尖端。我们发现了模空间的各种介子分支，其弦包含了具有不同数目的移动的D3-膜的翘曲变形锥。非移动的膜在阈值处形成BPS束缚态。在p可被M整除的特殊情况下，还存在一个一维重子分支，它的超引力簇--分解的翘曲变形锥最近被构造出来。翘曲变形锥是这些背景的一个特殊情况下，分辨率参数消失，2对称性恢复。我们研究了各种膜探针在变形锥上的分辨，并成功地将结果与规范理论相匹配。特别是，我们表明，径向潜力的D3膜在这个空间变化缓慢，提出了一个新的模型的D膜膨胀。
We carry out a thorough analysis of the moduli space of the cascading gauge theory found on p D3-branes and M wrapped D5-branes at the tip of the conifold. We find various mesonic branches of the moduli space whose string duals involve the warped deformed conifold with different numbers of mobile D3-branes. The branes that are not mobile form a BPS bound state at threshold. In the special case where p is divisible by M there also exists a one-dimensional baryonic branch whose family of supergravity duals, the resolved warped deformed conifolds, was constructed recently. The warped deformed conifold is a special case of these backgrounds where the resolution parameter vanishes and a 2 symmetry is restored. We study various brane probes on the resolved warped deformed conifolds, and successfully match the results with the gauge theory. In particular, we show that the radial potential for a D3-brane on this space varies slowly, suggesting a new model of D-brane inflation.
