# Duality walls and defects in 5d $\mathcal{N}=1$ theories

Journal of High Energy Physics, Jan 2017

We propose an explicit description of “duality walls” which encode at low energy the global symmetry enhancement expected in the UV completion of certain five-dimensional gauge theories. The proposal is supported by explicit localization computations and implies that the instanton partition function of these theories satisfies novel and unexpected integral equations.
