The Kapustin–Witten equations on ALE and ALF gravitational instantons
We study solutions to the Kapustin–Witten equations on ALE and ALF gravitational instantons. On any such space and for any compact structure group, we prove asymptotic estimates for the Higgs field. We then use it to prove a vanishing theorem in the case when the underlying manifold is R 4 or R 3 ×...
