Research
Singularities in Nonlinear Partial Differential Equations and the modern theory of the Calculus of Variations. At the core of my research is the study of "singularities", here defined to mean oscillation and concentration phenomena. In particular, I am interested in what can be rigorously proved about their "shape".
I have prepared a short general overview over my research.
On a more technical level, I work on:
- Efficient description of oscillations and concentrations
- Lower semicontinuity and quasiconvexity, also with the constraint of positivity of the determinant
- Compensated compactness and, more generally, restrictions on oscillations and concentrations
- Generalized Young measures
- Fine properties of functions of bounded variation/deformation
- Rigidity and softness, convex integration
- Rate-independent systems and their optimal control
Slides from talks about several aspects of my research can be found below.
