TITLE: Averages of central L-values of Hilbert modular forms
<BR><BR>

We use the relative trace formula to obtain exact formulas for central 
values of certain twisted quadratic base change L-functions averaged over 
Hilbert modular forms of a fixed weight and level. We apply these formulas 
to the subconvexity problem for these L-functions. This talk is based on 
joint work with David Whitehouse.
