DESCRIPTION:In recent years\, 4d Chern-Simons theory has emerged as a unif
 ying framework for a large class of discrete and continuous integrable sy
 stems in two dimensions. At the same time\, the Hitchin system remains th
 e most important example of integrable systems in two dimensions. This ra
 ises a natural question: can 4d Chern-Simons theory provide a new perspec
 tive on Hitchin systems?\nIn this talk\, after reviewing some background\
 , I will explain how 4d Chern-Simons theory can be used to derive an acti
 on whose field equations coincide with Hitchin’s equations on a closed su
 rface. I will also describe how the symplectic structure on the space of 
 solutions to Hitchin’s equations\, in an arbitrary complex structure\, ca
 n be recovered from the 4d theory. If time permits\, I will discuss how t
 he construction can be modified in the presence of ramification associate
 d with non-compact surfaces.
