Henryk Iwaniec, Philippe Michel, and K. Soundararajan

This workshop, sponsored by
AIM and the
NSF,
has the goal of providing
a description of *GL _{3}* automorphic forms and their L-functions
amenable to analytic number theorists and to explain the various approaches available to perform harmonic analysis on these spaces.
A second objective will be to discuss the extension of some of the important tools existing in the

In addition to introductory lectures, the workshop will be centered around various "practical activities" conducted by different, possibly non-disjoint teams of people: the goal will be to study some specific problem of interest, possibly including

- Develop usable tools to perform averages in families of
*GL*automorphic forms and in families_{3}*GL*L-functions in the various possible aspects: the goal will be to make as explicit as possible the spectral decomposition of the space of automorphic forms. A possibility would be to develop a workable form of the analog of the Kuznetzov formula in the_{3}*GL*context._{3} - Investigate the behaviour of the automorphic forms as one of the parameters attached to them vary.
- Prove non-vanishing results for
*GL*-L-functions in various aspects hopefully by using the mollification method; that should not be intrinsically difficult, the goal would be to get people used to the combinatorics underlying the Hecke algebra for_{3}*GL*._{3} - Try to understand the difficulty underlying more serious problems like the subconvexity problem in its various aspects.

The workshop will differ from typical conferences in some regards. Participants will be invited to suggest open problems and questions before the workshop begins, and these will be posted on the workshop website. These include specific problems on which there is hope of making some progress during the workshop, as well as more ambitious problems which may influence the future activity of the field. Lectures at the workshop will be focused on familiarizing the participants with the background material leading up to specific problems, and the schedule will include discussion and parallel working sessions.

The deadline to apply for support to participate in this workshop has passed.
