nLab magnetic eigenbrane

Idea

A brane that is taken to a tensor-multiple of itself under the action of a 't Hooft operators.

geometric Langlands correspondence	S-duality in N=4 D=4 super Yang-Mills theory
Hecke transformation	't Hooft operator
local system/flat connection	electric eigenbrane (eigenbrane of Wilson operator)
Hecke eigensheaf	magnetic eigenbrane (eigenbrane of 't Hooft operator )
