Extended holomorphic anomaly in gauge theory
The partition function of an N=2N=2{\mathcal {N}=2} gauge theory in the Ω-background satisfies, for generic value of the parameter β=−ϵ1/ϵ2β=−ϵ1/ϵ2{\beta=-{\epsilon_1}/{\epsilon_2}} , the, in general extended, but otherwise β-independent, holomorphic anomaly equation of special geometry. Modularity...

| Zusammenfassung: | The partition function of an N=2N=2{\mathcal {N}=2} gauge theory in the Ω-background satisfies, for generic value of the parameter β=−ϵ1/ϵ2β=−ϵ1/ϵ2{\beta=-{\epsilon_1}/{\epsilon_2}} , the, in general extended, but otherwise β-independent, holomorphic anomaly equation of special geometry. Modularity together with the (β-dependent) gap structure at the various singular loci in the moduli space completely fixes the holomorphic ambiguity, also when the extension is non-trivial. In some cases, the theory at the orbifold radius, corresponding to β = 2, can be identified with an “orientifold” of the theory at β = 1. The various connections give hints for embedding the structure into the topological string. |
