Abstract: Various energies of physical significance have been shown to effectively approximate the area functional, in codimension one and two.
These energies are defined on the set of functions on a given ambient manifold, and for critical maps they tend to concentrate towards a (possibly singular) minimal submanifold.
In this talk we answer the converse problem: we show that any nondegenerate minimal submanifold of the corresponding codimension does arise in this way.
The strategy is entirely variational and generalizes a recent work for geodesics (by Colinet, Jerrard, and Sternberg), by extending two key geometric measure theory results to arbitrary dimension.
