Algebraic Geometric understanding of the Fundamental group through Higgs pairs

The study of Higgs pairs has had many unexpected applications. One of the most spectacular, has been the understanding of the fundamental group from the algebraic geometric point of view, and identifying an action of $C^*$, which mimics the Hodge structure on cohomology. The lecture will seek to explain the construction of this new gadget and give one or two applications
