AdS${}_2$ Type-IIA Solutions and Scale Separation

Abstract

In this note we examine certain classes of solutions of IIA theory without sources, of the form AdS${}_2\times {\mathcal{M}}^{(1)}\times \cdots \times {\mathcal{M}}^{(n)}$, where ${\mathcal{M}}^{(i)}$ 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.
