我们进行了一个详尽的搜索与增广超对称的IIA和IIB超引力的解决方案。我们发现一个双参数家庭的IIB解决方案保留28个增压，以及其他几个IIA和IIB家庭的解决方案与24个增压。考虑到pp波解的简单性，这里描述的算法代表了一种对所有具有增广超对称性的解进行分类的系统方法。通过T-对偶的一些解决方案，我们得到精确的非pp波超引力解（8或16超荷），这可以解释为扰动的AdS-CFT对应无关的运营商。
We conduct an exhaustive search for solutions of IIA and IIB supergravity with augmented supersymmetry. We find a two-parameter family of IIB solutions preserving 28 supercharges, as well as several other IIA and IIB families of solutions with 24 supercharges. Given the simplicity of the pp-wave solution, the algorithm described here represents a systematic way of classifying all such solutions with augmented supersymmetry. By T-dualizing some of these solutions we obtain exact non-pp wave supergravity solutions (with 8 or 16 supercharges), which can be interpreted as perturbations of the AdS-CFT correspondence with irrelevant operators.
