Abstract: (Springer)
We show that the 5D Nekrasov partition functions enjoy the enhanced global symmetry of the UV fixed point. The fiber-base duality is responsible for the global symmetry enhancement. For SU(2) with Nf_{f} ≤ 7 flavors the fiber-base symmetry together with the manifest flavor SO(2Nf_{f} ) symmetry generate the ENf+1 {\mathrm{E}}_{N_{f+1}} global symmetry, while in the higher rank case the manifest global symmetry of the two dual theories related by the fiber-base duality map generate the symmetry enhancement. The symmetry enhancement at the level of the partition function is manifest once we chose an appropriate reparametrization for the Coulomb moduli.
