Holographic duals of Boundary CFTs

Understand

New families of regular half-BPS solutions to 6-dimensional Type 4b supergravity with $m$ tensor multiplets are constructed exactly.

• Their space-time consists of $AdS_2 \times S^2$ warped over a Riemann surface with an arbitrary number of boundary components, and arbitrary genus.
• The solutions have an arbitrary number of asymptotic $AdS_3 \times S^3$ regions.
• In addition to strictly single-valued solutions to the supergravity equations whose scalars live in the coset $SO(5,m)/SO(5)\times SO(m)$, we also construct stringy solutions whose scalar fields are single-valued up to transformations under the $U$-duality group $SO(5,m;\bZ)$, and live in the coset $SO(5,m;\bZ)\backslash SO(5,m)/SO(5)\times SO(m)$.
