I will discuss some new results for gradient field models with uniformly
convex potentials. A connection between the scaling limit of the field and
elliptic homogenization was introduced more than twenty years ago by Naddaf
and Spencer. In joint work with Wei Wu, we take another look at their ideas
in light of recent work in quantitative homogenization.

Joint IAS/Princeton University Number Theory Seminar

Topic:                    Local aspects of Venkatesh's thesis.

Speaker:              Yiannis Sakellaridis, Rutgers University

Time/Room:       4:30pm - 5:30pm/Simonyi Hall 101

The thesis of Akshay Venkatesh obtains a ``Beyond Endoscopy'' proof of
stable functorial transfer from tori to ${\rm SL}(2)$, by means of the
Kuznetsov formula. In this talk, I will show that there is a local statement
that underlies this work; namely, there is a local transfer operator taking
orbital measures for the Kuznetsov formula to test measures on the torus.
The global comparison of trace formulas is then obtained as a Poisson
summation formula for this transfer operator.
