On the singular sets of solutions to the Kapustin–Witten equations and the Vafa–Witten ones on compact Kähler surfaces

This article finds a structure of singular sets on compact Kähler surfaces, which Taubes introduced in the studies of the asymptotic analysis of solutions to the Kapustin– Witten equations and the Vafa–Witten ones originally on smooth four-manifolds. These equations can be seen as real four-dimensio...
