There exists also a (conjectural) Geometric Langlands correspondence related to dualities in the 4-dimensional quantum field theory (see Gauge Theory and the Analytic Form of the Geometric Langlands Program by D.Gaiotto E.Witten).
1) The stability of characters of representations of reductive groups over local non-archimedian fields and the related question about the presentation of characters as linear combinations of character sheaves.
2) The geometric construction of the L-functions of representations of reductive groups over local non-archimedian fields and
3) The extension of the Langlands conjecture to the new area of representations of Kac-Moody groups.
The main objective is to advance the area of the representation theory through the application of concepts and results from Algebraic Geometry and Category Theory.
In all of these three areas we obtain new and important results. In the part 1) we defined the notion of character sheaves for groups over local fields. In the part 2) we provided a geometric construction of the L-functions in a number of new and important cases and In the part 3) we developed a completely new theory of the Langlands correspondence for Kac-Moody groups.
