论文摘要
在此注释中，我们检查了IIA理论的某些类别的解决方案，没有来源，形式为$ _2 \ times {\ cal m}^{（1）} \ times \ dots \ times \ times \ times \ times {\ cal m}^{（n）} $，$ {\ cal m}^{\ cal m}^{（i）} $ riiemann spaces我们表明，在不同因素之间可以获得大量曲率的层次结构，但是ADS $ _2 $的标量曲率的绝对值必须与所有其他因素的标量曲线的绝对值相同或大。
In this note we examine certain classes of solutions of IIA theory without sources, of the form AdS$_2\times {\cal M}^{(1)}\times \dots \times {\cal M}^{(n)}$, where ${\cal M}^{(i)}$ are Riemannian spaces. We show that large hierarchies of curvatures can be obtained between the different factors, however the absolute value of the scalar curvature of AdS$_2$ must be of the same order or larger than the absolute values of the scalar curvatures of all the other factors.
