Automorphic forms and harmonic analysis on covering groups

This workshop will be devoted to discussing extensions of the
the Langlands program to nonlinear groups in some generality. An
important example of such group is the metaplectic group: the
two-fold cover the symplectic group over a local field.
The focus of the workshop will be on foundational questions in the
harmonic analysis and the theory of automorphic forms on such groups.
The main topics for the workshop are:
While there have been many attempts to extend the Langlands philosophy
to covering groups in the past, these were largely confined to
specific families of examples.
- basic results in harmonic analysis and a theory of endoscopy for
- formulation of a local Langlands correspondence for nonlinear groups;
- a theory of types for nonlinear groups;
- the trace formula and the structure of automorphic discrete spectrum.
In the past year, there have been a number of encouraging developments
regarding a general treatment. These developments strongly suggest
that a workshop devoted to the above foundational issues will be
especially timely. This workshop will gather the experts working on
different aspects of the problem, in order to take stock of and
consolidate these early progresses and to formulate the key questions
to be addressed in the immediate future.
