Typo regarding complex structures.
]]>Added link to nonabelian Hodge theory.
]]>Added links to D-module and Hecke eigensheaf. Added the Hausel-Thaddeus paper and the Witten survey as references.
]]>Changed Hecke operators to Hecke correspondences as a page for the former does not exist.
]]>Added links to Hecke operators and quantization via the A-model.
]]>Trying to correct the link to hyperkahler manifold.
]]>Adding links to Wilson loops and ’t Hooft operators.
]]>Added connection to geometric Langlands and how to associate a Hecke eigensheaf to a local system.
]]>Corrected link to Frenkel survey.
]]>Added a symbol for the Hitchin moduli space and made note of the gauge group . Made mention of S-duality manifesting as mirror symmetry between the Hitchin moduli spaces for and its Langlands dual. Added link to Frenkel survey.
]]>Added the form of the 4-dimensional spacetime on which the Kapustin-Witten TQFT is defined. Added that the Kaluza-Klein compactification is on , and that the resulting effective field theory on can be given by the sigma model whose target is the Hitchin moduli space.
]]>stub for Kapustin-Witten TQFT in order to supply some links for this TP.SE question
