AdS5 compactifications with punctures in massive IIA supergravity

Understand

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.
