Descripción del proyecto
The goal of this research proposal is to advance the calculus of variations of area in codimension higher than one, specifically existence and regularity of its critical points (minimal submanifolds) and properties of its gradient flow (mean curvature flow). These are central objects in mathematics since three centuries and contributed to the birth of geometric analysis, geometric measure theory, and calculus of variations. Their (non-)existence often reveals deep links between small-scale geometry (curvature) and large-scale structure (topology). While the hypersurface case is by now well understood, with several deep results in the last two decades, very little is known in codimension at least two, especially for unstable submanifolds not minimizing area. Several projects will focus on the intimate link between area and some well-known physical energies: phase transitions are understood to give diffuse approximations of hypersurfaces, while vortices in models of superconductivity relate to codimension two submanifolds. An energy proposed by me and D. Stern in this context is the abelian Higgs model, which I plan to use to extend the Lagrangian mean curvature flow past singularities and to relate stability and regularity of minimal submanifolds, which are two long-standing questions in geometric analysis (among other projects), by exploiting the much richer structure given by the PDEs solved by critical points of this energy. I will also look at candidates in codimension three and higher, inspired by energies from gauge theory and others of Ginzburg–Landau type, relating stability and minimality in critical dimension and attacking other basic open questions. Finally, I will also work on another set of projects exploiting parametrized varifolds, a variational object pioneered by me and T. Rivière combining advantages of the parametrized and intrinsic viewpoints, to study Lagrangian surfaces and minimal submanifolds of higher dimension
