Course/Module description:
The motivation for this class is the classical Plateau's problem. Given a k dimensional sub-manifold N in R^n, find a (k+1) dimensional sub-manifold M having the minimal volume among all the sub-manifolds with boundary N.
In order to address this problem, we will develop weakened notions for sub-manifolds (Integral varifold, Integeral currents), which employ the language of measure theory, and study their properties.
At the end of the class, we hope to give the following answer to Plateau's problem:
There always exists a weak solution to Plateau's problem. If k&eq;n-2 (i.e. when we search for a hypersurface minimizing volume), the solution is a smooth hypersurface, away from a set of co-dimension 7. In the general case, we will show that the solution is smooth on an open dense set.
