Abstract
We calculate the leading weak-coupling instanton contribution to the modulispace metric of N = 2 supersymmetric Yang-Mills theory with gauge group SU(2) compactified on ℝ3 × S1. The results are in precise agreement with the semiclassical expansion of the exact metric recently conjectured by Gaiotto, Moore and Neitzke based on considerations related to wall-crossing in the corresponding four-dimensional theory. © SISSA 2010. © SISSA 2010.
