# AdS5 compactifications with punctures in massive IIA supergravity

## TL;DR

This paper constructs explicit AdS5 solutions in massive IIA supergravity that are dual to six-dimensional N=(1,0) theories compactified on Riemann surfaces with punctures, revealing new classes with diverse brane configurations.

## Contribution

It simplifies previous analyses and finds three explicit classes of solutions with brane setups, including smeared D4-branes and novel dual field theory interpretations.

## Key findings

- Three classes of explicit AdS5 solutions with different brane configurations.
- Identification of a class dual to E-string theories coupled to quiver gauge theories.
- A class with central charge scaling as n^{5/2}, indicating a 5D origin.

## Abstract

We find AdS5 solutions holographically dual to compactifications of six-dimensional N=(1,0) supersymmetric field theories on Riemann surfaces with punctures. We simplify a previous analysis of supersymmetric AdS5 IIA solutions, and with a suitable Ansatz we find explicit solutions organized in three classes, where an O8--D8 stack, D6- and D4-branes are simultaneously present, localized and partially localized. The D4-branes are smeared over the Riemann surface and this is interpreted as the presence of a uniform distribution of punctures. For the first class we identify the corresponding six-dimensional theory as an E-string theory coupled to a quiver gauge theory. The second class of solutions lacks D6-branes and its central charge scales as $n^{5/2}$, suggesting a five-dimensional origin for the dual field theory. The last class has elements of the previous two.
