The geometry of convolution inequalities
The Brascamp-Lieb inequalities for multiple integrals describe versions
of the H\"older inequality in directions of the Euclidean space. Established first
by symmetrisation, optimisation of Gaussian kernels or optimal transportation,
recent developments by E. Carlen, E. Lieb, M. Loss and J. Bennett, A. Carbery,
M. Christ, T. Tao put forward a new approach by evolution along the heat
equation. In particular, this proof relies on suitable geometric decompositions
of the identity, which give direct access to some famous convolution inequalities
in Harmonic Analysis with their best constants.

On the vanishing viscosity method in fracture mechanics
The Griffith criterion is an energetic fracture criterion which is
frequently applied to decide whether a preexisting crack in an elastic
body is stationary for given external forces. Moreover, a
great number of models rely on the Griffith criterion and
describe the time evolution of a crack. In this lecture we model the
evolution of a single crack as a rate-independent process based on the
Griffith criterion and discuss different possibilities for setting up
such models. In the last years mainly two approaches were followed: Models based on
global energy minimization (elastic energy + dissipation)
and models based on a local description of force balance type.
Our focus lies on the analysis of local models which
appear as the limit of evolution models with a viscous regularization.
Moreover, we discuss the convergence of fully discretized models
(i.e. with respect to time and space) to the local model.
The convergence proof relies on new regularity estimates for the
elastic fields close to the crack tip taking into account
non-penetration conditions on the crack faces.
Finally an outlook to phase-field like damage models will be
given. The advantage of these models is that no a-priori knowledge
on the crack path is needed.
The research is joint work with A. Mielke, R. Rossi, A. Schr\"oder
and C. Zanini.

On the ultrametricity problem in spin glass theory
Ultrametricity is a very puzzling open problem in
spin glass theory. We describe the problem, discuss
why it is thought to be important, and present
attempts to shed some light on it.
