Description

I will give an overview of the integrability properties of ½ BPS Nahm pole defects in N=4 SYM paying special attention to the case of Gukov-Witten surface defects which have only very recently been studied in the integrability context. Furthermore, I will discuss how localization results for one-point functions in these set-ups imply an intriguing structure of perturbation theory that might help us getting new insight on
wrapping corrections.
