Research
The subject of my research is the Plateau problem in some of its variants. There are many of them but the general idea is the following: given a boundary set B, one tries to minimize the area of a set E bounded by B. Part of the problem is hidden in the choice of a suitable definition of “area” and “bounded by”. In particular we are interested in a formalisation, similar to the Almgren's one, where the area is the Hausdorff measure and the boundary condition is expressed in terms of a one parameter family of deformation. We are concerned in the existence of minimisers (a property that is still widely unknown both in Almgren's and in size minimizing current framework) as well as in minimiser's (and, in general, almost minimiser's) regularity properties, in particular near the boundary, another question that has not been investigated very much. We also focused on a slight variant of the problem called “sliding boundary”. In this new setting, after fixing a set L, we only consider those modifications f such that f(x) sits in L whenever x belongs to L, and the functional we want to minimise is modified on L by multiplying the Hausdorff area by a parameter 0
