Abstract. In this talk, I will discuss subleading corrections to the large-N partition functions of 3d SCFTs of class R, obtained from wrapping M5-branes on certain 3-manifolds. The corrections are obtained in a holographic setting by considering higher-derivative terms in the bulk 4d gauged supergravity theory. The framework can be used to study the 3d-3d correspondence relating the partition functions of class R theories to topological invariants in Chern-Simons theory on the wrapped 3-manifolds. This higher-derivative logic can also be extended to five bulk dimensions, where we use it to derive subleading corrections to the central charges of 4d N=2 SCFTs. Finally, I will discuss the details of these corrections for the black string, and the corrected holographic RG flow across dimensions.
