The construction of critical points of the area, that are not necessarily area minimizers, typically requires to pass to the limit a sequence of almost critical submanifolds with area bounds, in order to find a limit that is critical for the area. To this aim, currents are not very effective, since the mass is only lower semicontinuous and we could end up with a trivial limit. This is not an...
Our aim is to introduce the computability-theoretic concept
'Kolgomorov complexity' and show how it can be used to obtain
interesting results in Geometric Measure Theory.

This course presents a unified approach to extending boundary data from rough domains into the interior, with a focus on applications to boundary value problems for elliptic operators. We study recent advances in constructing \emph{smooth harmonic-type extensions} of BMO and ( L^p ) functions from the boundary ( \partial \Omega ) of a domain ( \Omega \subset \mathbb{R}^{n+1} ), where the...

The classical isoperimetric inequality in Euclidean space $\mathbb{R}^n$ states that among all sets of prescribed volume, the Euclidean ball minimizes surface area. One may similarly consider isoperimetric problems on more general spaces, such as on the $n$-sphere $\mathbb{S}^n$ and on $n$-dimensional Gaussian space $\mathbb{G}^n$ ($\mathbb{R}^n$ endowed with the standard Gaussian measure)....
