Description

We review recent work [1,2] on obtaining a realisation of the Ω-background in terms of a special series of higher-derivative generalised F-terms in the effective N = 2 supergravity action. We discuss the motivation behind the identification of these couplings, their relation to the Nekrasov partition function and connect them to a worldsheet approach towards the refined topological string.
