Gradient Gibbs measures with disorder

ESB 2012

Abstract
We consider  in uniformly strictly convex potentials case  two versions of random gradient models. In model A) the interface feels a bulk term of random fields while in model B) the disorder enters though the potential acting on the gradients itself. It is well known that without disorder there are no Gibbs measures in infinite volume in dimension d = 2, while there are gradient Gibbs measures describing an infinitevolume distribution for the increments of the field, as was shown by Funaki and Spohn. Van Enter and Kuelske proved that adding a disorder term as in model A) prohibits the existence of such gradient Gibbs measures for general interaction potentials in d = 2. Cotar and Kuelske proved the existence of shiftcovariant gradient Gibbs measures for model A) when d > 2 and the expectation with respect to the disorder is zero, and for model B) when d > 1.
In recent work, we prove uniqueness of shiftcovariance gradient Gibbs measures with expected given tilt under the above assumptions. We also prove decay of covariances for both models.
We will also discuss in the talk the case of nonconvex potentials with disorder.
This is partly based on joint work with Christof Kuelske.

Remarks on the local Langlands conjectures.

Math Annex 1100
Fri 5 Sep 2014, 3:00pm4:00pm
Abstract
The Langlands program, initiated in the 1960s, is a set of conjectures predicting a unification of number theory and the representation theory
of groups. More precisely, the Langlands correspondence provides a way to interpret results in number theory in terms of group theory, and vice versa.
In this talk we sketch a few aspects of the local Langlands correspondence using elementary examples. We then comment on some questions raised by the emerging "mod p" Langlands program.
