AdS 2 solutions and their massive IIA origin

摘要

A bstract We consider warped AdS~(2)× ?~(4)backgrounds within F (4) gauged supergravity in six dimensions. In particular, we are able to find supersymmetric solutions of the aforementioned type characterized by AdS~(6)asymptotics and an ?~(4)given by a three-sphere warped over a segment. Subsequently, we provide the 10D uplift of the solutions to massive type IIA supergravity, where the geometry is AdS~(2)× S _(3)× S ? 3 $$ {ilde{S}}^3 $$ warped over a strip. Finally we construct the brane intersection underlying one of these supergravity backgrounds. The explicit setup involves a D0-F1-D4 bound state intersecting a D4-D8 system.
