abstract
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.

Scale separation on AdS$_3\times S^3$ with and without supersymmetry
The complete Kaluza-Klein spectrum of six-dimensional Salam-Sezgin supergravity on AdS3 times a squashed three-sphere is computed; in the large-squashing limit, all but a small set of low-energy fields acquire infinite mass.

Integer dual dimensions in scale-separated AdS$_3$ from massive IIA
Massive IIA flux compactifications on singular and Joyce G2 orbifolds yield scale-separated AdS3 vacua whose dual operator dimensions are integer up to parametrically small corrections.

Universal Cosmologies
For open FLRW universes in two-scalar exponential-potential models from 10d IIA supergravity, the late-time attractor sets the effective exponent to the shortest vector to the convex hull of potential exponents, givin...
