Abstract

The study of the calculus of variations is largely motivated by physical phenomena which can often be seen through the lens of minimizing a system’s energy. In this paper, we will survey the 19th Hilbert problem and the revolutionary approach by Ennio De Giorgi to solve it. The 19th Hilbert problem asks whether minimizers of regular variational problems are necessarily analytic. In simple terms, if we have a function that minimizes a nicely behaved functional, are the minimizers themselves nicely behaved? The methods established by De Giorgi have greatly influenced the current study of nonlinear elliptic partial differential equations.
