${\cal N}=(2,2)$ AdS$_3$ from D3-branes wrapped on Riemann surfaces

We construct $\mathcal{N}=(2,2)$ supersymmetric AdS$_3$ solutions of type IIB supergravity, dual to twisted compactifications of 4d $\mathcal{N}=4$ super-Yang--Mills on Riemann surfaces. We consider both theories with a regular topological twist, and a twist involving the isometry group of the Riemann surface. These solutions are interpreted as the near-horizon of black strings asymptoting to AdS$_5\times \text{S}^5$. As evidence for the proposed duality we compute the central charge of the gravity solutions and show that it agrees with the field theory result.
